Headers, of course, were used on the Trans-Am cars back in the day. Probably any kind of header
under the sun was tried at one time or another. Starting in June, 1968 when Jere Stahl sent off
his first set of road race headers to Roger Penske, Stahl headers were some of the best performing
and most popular headers in use among Trans-Am teams.

Here's a nice set of restored Stahl headers owned by Robert Lodewyk. Jere Stahl tells me these
are the drag racing version of his Camaro header.


A closer look at the header flanges. Same header flanges used by Douglass Muffler Mfg.


Robert Lodewyk also owns this set of original Stahl road race headers which came off the '67 Trans-Am
Camaro raced by Hugh Harn, who raced out of the San Francisco Region of the SCCA.


Here's an original '69 advertisement for Stahl headers.

Thanks Jon for posting these pictures.

My car as well as Hugh Harns 67 Z ran in the Sears Point race in September of 1969. Its quite possible that these headers were on Harns car at that time. Now 40+ years later they will be on a car it run against back then---Kinda COOL Smiley

These are the factory-supplied GM headers for the '67 Z-28 Camaro. Ron Ogilvie, parts manager for
Bill Thomas Race Cars circa September '66 - August '69, tells me that these headers were designed
at BTRC and built by Douglass Headers (Douglass Muffler Mfg). Ron says that he personally painted
the headers the silver-blue color and placed each set in a burlap bag for delivery to GM. These headers
were probably the most commonly seen headers on Trans-Am cars up until Stahl started providing
Camaro racing headers in mid-'68.

Factory supplied instructions on how to do the installation. The headers were furnished "loose" and
it was up to the dealer or owner to install them. No headers were installed on the assembly line.




Here's an original set of GM header gaskets. The heat resistant material is Raybestos-Manhattan No. A 56.

A little intro from Bill Thomas, found in his '70 catalog. There are probably not enough superlatives to say
about this man who did so much for Chevrolet performance back in the late '50's and throughout the '60.

Michigan-based Kustom Headers became the supplier of Z28 headers to GM starting in 1968.
I don't know if it was based strictly on cost but certainly that probably factored into the
equation. The most high-profile team to use Kustom Headers were the "Chaparral" Camaros
of Jim Hall.


Close-up view of a GM part number on the header flange. For some reason there are a few
different GM part numbers for these Kustom-built headers. These were also available direct
from Kustom and those are stamped KH-37 on the flange.




Some Kustom header flanges are squared-off on the ends and some are pointed.
There does not appear to be any clear reason why. Note the 4-bolt collector flanges.




Info provided in the '68 Z28 brochure. Note the different part number(s).


From the 1974 Kustom Headers catalog...


Here's Gene Harrington's '69 T/A camaro sporting a Kustom Headers decal
on the front fender, behind the front tire.

great stuff -thanks for posting

In the Stahl ad they mention Tony Pizzi and Don Yenko

Tony ran the 1967 drag car sponsored by Yenko Sports Cars

I think this was an early Z/28 as later in 1967 Yenko sponsored Dick Harrell in a 427 Camaro

They mention Don's Daytona win which was the 1969 Citrus 250 Don won in a ex Smokey Yunick 68 Camaro

Nearly 20 years ago, Dick Lewis from Ohio went to the effort to get 25 sets of Bill Thomas headers reproduced
using 25 sets of original upper header flanges that he had acquired over many years of being in the Camaro
hobby. There was talk of producing another 25 but the second set was not going to have the original upper
flanges. I am not sure if those 25 got made or not. These headers were copied directly from the original set
which are currently owned by Rick George of Rick's Camaros. Years later, Larry Christensen also reproduced
an unspecified amount of these headers. The headers below are from the first set of 25 reproduced by Dick
Lewis and were sold to Frank Dihartce. Thank you Frank for sharing these photos with us.

1967-1968 Hedman Hedder ads. These were known more for ease of fit than outright performance but I have included
them here for identification purposes in case somebody has an old set they are trying to identify by the bends of the tubes.

Here are some very neat NOS Headers by JR, made by Beeline Engineering out of Hillsdale, Michigan.
I have seen them called JR Headers and Headers by JR but they were not marketed as Beeline Headers
even though they were the manufacturer. These NOS headers were obviously never installed and still
have the instructions, header gaskets, etc. It is neat to see the Raybestos Manhattan #A56 gasket
material shown earlier for use with the Douglass/Bill Thomas headers. These authentic vintage headers
are owned by Roger Hefty and I thank him very much for sharing these photos with us.

Are there comparable versions of any of the road racing headers such as the ones in this thread being produced today? Could you find similarly priced road race headers that might even be better? Amazing work!

I believe they are still reproducing the Kustom and Bill Thomas/Douglass headers on a onesie-twosie basis but the price is not anywhere close to what they were originally. I think the price is $1500 or above. The other headers shown in this thread are not being reproduced. Hooker and Hedman are still around but their headers do not look the same (different flanges and pipe bends) as they did in the old days. You might be able to find used examples, which is why I have chosen to include pages from their advertisements and catalogs, making them easier to identify when and if they are found.

Mr. Mello , you would seem to be the one to ask. Who made these ? Appears to be a Hooker #. Original owner stated when he ordered the Z he also ordered headers through the dealer. When he picked the car up they were in the trunk ,dealer would not install. I know they are not Stahls but am curious. None the less they are going back on, have been with the car since 68. any info would be appreciated.

I know I'm not Jon but I used to work at Holley as the tech support for Hooker & flow tech headers..  The 2204 is the part number for Hooker headers..  If I'm not mistaken they are the super comps with 1 3/4 primaries & 3" collectors & were able to be used with ps but not a/c.  I'm going off memory so I might not be 100%.

Janobyte, it is my opinion that the headers you have are Hookers since the part number seems to be one of theirs and later Hookers did
use that type of flange at the cylinder head interface. The '67 Hooker flanges are seen on the first page of this thread. The flange changed
for '68 due to Chevy putting a temp sender boss in the side of the cylinder head. The Hooker catalog below shows the style of flange that
Hooker was using from '68 to at least 1971 and probably later. I think your headers are mid '70s at the earliest. Just my 2 cents worth.

You are correct ,they are 1 3/4 "   I was pretty sure but not 100 % they are Hooker Super Comps. More important I am fishing for a date. Not to say the original owner is telling a story but by 76 ( when my father purchased it) the car changed hands 3 times and I can surmise they were replaced. At first I believed possibly the dealer ordered the headers as they did the Sun tac. Sadly that car may of had Stahls which are long gone. This is why I truly appreciate the wealth of knowledge on this site. The truth is in the catalogs.

It may well be that your car came new with the factory headers in the trunk so the original owner may
not necessarily be lying. With the car changing hands several times before your dad got it 7+ years later,
the headers could have been replaced by one of the interim owners and the original owner would have
been none the wiser. Stahl headers were never used by GM as their OEM supplier of headers. For the
'68 model year, Kustom headers would have been the brand that was offered.

The history lessons here never get old to me .  Makes sense there was a header swap somewhere up stream. #1 owner tracked me down a few years ago. We spoke some time and he wanted to meet but I really have no interest in selling , where  this "meeting" was eventually going.

back in the day I was a stocking dealer for KUSTOM headers. jerrys stahl headers were good but they were heavier than some other brands and extra weight on the front of a race car is not good.

Kustom made good headers and they got pretty popular in the early '70s but then it all fell apart. I don't know why but I guess it must come down to mismanagement.

Here are pages from the 1971 Cyclone headers catalog. Dick Harrell ("Mr. Chevrolet") and some of his
drag cars were featured inside the front cover. The 1970 Mopar Trans-Am cars used Cyclone headers.

A good look at the style of flange used by Cyclone in the early '70s for small block Chevys.
Note the markings in the first picture below that show equal length primary tubes.

I see someone out there is welding up the Kustoms. By no means am I trying to be insulting ,but what is the quality ? Tig welded ? Flanges thick and true? Tube size and gauge ? I'm interested the nostalgic look of them.  Never putting the cast iron exhaust manifolds back on it---never. Really digging the "street" T/A look ! That's what these Z's were built for, correct?

Both the Bill Thomas/Douglass reproduction headers and the Kustom reproduction headers are done with a high level of craftsmanship.
I got my current set of reproduction headers through Larry Christensen when he had his Camaros Plus business several years back. He since
sold the business to Steve Pelletier and the phone number is 303-420-6229 (Colorado). I would assume Steve P could either sell you the
headers or direct you to whoever is doing them, whether that is still Larry's sideline or somebody else's. They're not cheap but they are
well done and I think you'll be happy to own them.

Did someone say "Street T/A"?  Camaro guys have it easy as far as header go. Just be glad thay didn't use a set up like this. I just finished them for my street T/A Boss. I probablty have close to $1,800 in just stainless tube and mufflers. Dual 3" pipes out each side should be loud enough.

Beautiful job and an incredible amount of work to fabricate an exhaust system like that. I'm thankful
the Camaro teams never crafted something as complex as that although I do think it is very cool.

Larry was a big name rail/funny car chassis builder in the 60's through early 80's in N/E Ohio. Designed the Lakewood bell housing , worked for Mickey Thompson until his death. Redoing Jeg ( Coughlin' s ) nostalgic funny car. An artist and craftsmen ,not a self promoter. Right in the middle of drag racing back in the golden years. Calling him after the holiday about these pipes. Point being one of those wonderful old timers that can scratch a sketch on scrap paper and , produce a product with 0 tolerance.

Sounds like Larry Sikora certainly has the talent to make headers for you. I'll try and do some more digging
to verify if the factory headers are still being reproduced. I think they are but might be wrong about that.

I am trying to identify some headers I have that came with my 68 302 car.  They have the square 4 bolt collectors and the flanges are separated on the head side, meaning the middle primaries are not connected to the outer two.  Ill post pics tomorrow.

They could also be '70s-era BlackJack headers as the same description fits. The BlackJack headers were white back then and I think they are black now.

Are you saying they are older than 1975 or newer than that? No, I don't have a catalog for BlackJack headers but have seen
old ads for them and confirmed the details that way. Post the pics and eventually we will get a definitive answer for you.

The guy at this thread... http://www.hotrodders.com/forum/appliance-headers-first-gen-camaro-156947.html
says he has Appliance headers and they look basically like yours. However, he bought them as used items in a
junkyard and he may not necessarily be right. Below are two photos of his headers and they match up well with
yours. I think his are actually BlackJack headers with the optional "Alumacoat" and yours may be the standard
BlackJack headers without the special coating. I don't have a lot of '70s magazines but I will keep looking
around to see what else I can turn up.





Here is a Summit Racing Equipment ad for BlackJack headers from December 1981. The front tube (#2) is not
routed quite the same as yours but since it is a drawing, it may be just drawn incorrectly. The tiny color ad below
that shows the driver's side Alumacoat BlackJack header and that seems to be a match.

I definitely see the similarities but I also see that the merging of the colllectors are different in lengths.  Not sure if that could have been a manufacturing change or what but they are very similar.

Good catch on the different length. We'll get an answer sorted out eventually.

Some NOS header "singles" from the Robert Lodewyk collection. These came off a wall at a defunct speed shop as I understand it. The first
two pics are of a Douglass H504-DU Chevelle small block header, passenger side. The other two headers are thought to also be by Douglass
but there are no part number tags on them and we're not sure why they are painted a different color than the Chevelle header.

the thinking now days about headers is not equal length as it wideneds out the torque curve.  the new grand am corvette race cars even have unequal length fuel injection intake stacks for the same reason

Yes, sometimes you'll see some strange and/or funny tubing bends on headers that are trying to have
equal length. I can't think of too many crazier looking bends than on the Stingray headers shown below
in a June '68 ad by Headers by Ed (Racing Exhaust Specialties). Note the Douglass style upper flanges.





This 1969 ad shows Z-28 street headers. Here it looks like the Douglass style upper flanges have been
replaced with the early style Hooker Header flange but with a circular notch cut-out for the temp sender.
These guys look like they made very good headers. (Jon Mello Collection)

I would think a wider torque curve would be desirable, no?

Mickey Thompson came out with his "Super Scavenger" headers in 1968. A novel idea that didn't
last more than a couple of years. I believe M/T painted his headers orange. (Jon Mello Collection)

My bad. I misunderstood what you said the first time. I don't know why but for some goofy reason I came away thinking you were saying a broader torque curve was not good.

September '69 ad for Cragar headers



An original set of Cragar headers. They appear to use the same head flange that Hooker did at this time.

I noticed Jere Stahl of Stahl headers has an inventory reduction sale going on. In particular, I
noticed a couple of his #110 road race Camaro headers and the price was dirt cheap if you are
looking for these. It should be noted that the #110 headers sit a full inch higher in the chassis
and won't fit in a Camaro with a stock floor pan. You would have to have a car with the tunnels
in the floor like some of the old Trans-Am cars had. A good deal for somebody with a race car.

Jon,
they also call out for spread port heads..  You can make them work on stock heads with adapters but not intended for that & it could cause some fitment issues with the steering box & steering components.
