I'm very happy that Phat has joined the forum. His contributions  are typical of his "exhaustive " 😂 research.

Another easily identifiable feature is at the top of the first color picture - the long front pipe which would be part of the driver side pipes is also seen in the last b&w photo on the previous page of this thread. That picture is easy to pick out - the alternator is at the front. The long pipe starts at the front and is on top of all the other pipes. You can easily see its length as naturally it would be longest. It is also different than many other systems where the front pipe would go down at a much sharper angle and would then become more horizontal as it goes under the other pipes. Stahl and Douglass systems on small blocks come to mind with the more common layout I just described.
 The system where the pipes are brazed to the sectioned cast iron exhaust manifold outlets as seen in the black and whites of the Warren Prout Javelin cause the pipes to hug the block and the small diameter is also apparent. I can illustrate later how small the headers are when taking a set of measurements of my own AMC free flow manifolds. The small size would favor velocity and power as the manifold spigot conforms to the dogleg outlet much more faithfully than do headers and the gases are channeled at high speed into the straight pipe run without losing velocity. The Javelin design brings to mind the "zoomies" on old top fuel dragsters.

I can't take screen shots at this time. However if you look at the top EBay photo above (Jon's screenshot) either group shot of pipes, the lower middle pipe for the passenger side shows one pipe snaking under the other just like the second b&w photo shows. The b&w photo shows the outline of the R&D number on each head pipe ( evident in photo 2). The segments that each pie is made from are very evident in the top photo in Jon's screenshot and also evident in the b&w photo( number 2).
More to follow.

Correction - the 298 is actually part of the RD number sequence and upon closer inspection appears to be "293". Photo 5 in the ad is actually for the opposite side, the driver's side. Photos 1 and 2 are actually the same side as the middle black and white photo. The last b&w photo is the driver side, same as photo 5 in the ad. As stated before I will point out other comparisons between ad and photos posted here. My apologies for adding some confusion in my post earlier this evening.

I have the whole group of photos from the Ebay sale saved. When it was posted on another forum by another AMC devotee I saved all the photos. I haven't had access to my computer since my wife and I moved and we are still organizing. However, before going into a more in depth study I can point out some immediate details that tie these headers to the ones in the black and white photos from the first page of this thread. The spigot shaped head at the top of the pipes. The seamed sections of each pipe. The numbering system on the spigots. These are definitely not Penske headers as described in the EBay ad. Penske race parts are marked with "RP", for Roger Penske. There are further characters that follow on Penske race parts from the era.
Back to the headers in the ad. I have the listing saved in "my EBay". If one looks at the 5th photo in the link, https://www.ebay.com/itm/ORIGINAL-PENSKE-DONAHUE-AMC-JAVELIN-TRANS-AM-303-SHORT-DECK-HEADERS/112609669098?hash=item1a380f2fea%3Ag%3Ay6IAAOSwCJxZ6Ngq&_nkw=penske+javelin&rt=nc&redirect=mobile, there is a number, "298", above the RD sequence in the same photo. A similar appearing raised set of marks are visible in the middle black and white photo on the previous page of this thread. The height of the markings are also in a very similar position relative to the safety wired bolts as the markings are positioned in photo 5 of the EBay ad. Also just visible in the b&w photo in this thread below the 3 digit number is the raised outline of at least one character below the 3 digit number, similar to the second row of characters seen in photo 5 of the ad. There are more photographic similarities between the ad and the black and white photo in this thread, but I will discuss that later.

Hello All,
Been away for awhile. Regarding the TEAM AMX, about 3 or so years ago Mike Randall confirmed in a telephone interview that I had with him that at some point the car had been accidentally allowed to go to a wrecking yard where it was crushed. Mike did say that he's planned to create a replica of the car.

Regards,
Steve

Yes, like both above examples. The six spokers appear to take the Libre bolt hole circle concept one extra step beyond by machining the pad above a completely concentric ring separating the spokes from the bolt hole circle.

I think those are the torque thrusts and perhaps 200s's with the pie cutouts on the backside of the bolt hole circle. I seriously doubt ones like the one pictured were the break prone ones. If there was another version with the rib in the middle also they would be bullet-proof, hence the question I started with about versions existing with the Libre and six spoke feature.

If you look at the picture in the TA wheels section you can see why the spokes broke where they did.

That has the full bolt circle and thick spoke sides. A definite improvement over some other ones.

Are there any versions of the daisy wheels that have a center reinforcing rib under each spoke and a full circle bolt hole plate without the reliefs cut in on the underside at the "nose" of each daisy spoke? In short, are there any 200S or 200P wheels that mimic the ARE roadracing 4-hole Libres:http://www.zparts.com/zptech/comparisons/wheels/pages/are_vs_noname_back.html

Yes, other details that separate dogleg castings from rectangular castings, which I'm putting together photographically, will bear this out.

I would like to find out if there are further pictures of the engine bay from this series. It appears the original photographer used a lens filter which rendered parts of the same color as very dark, so dark that there are little to no detail features in the shadows despite using Photoshop and the like to pull those features up. The cylinder heads have markings that differentiate between dogleg and non-dogleg. Without the detail in the cylinder head shadows though, my conclusions will center entirely on the exhaust manifold details.

Regarding the Paschal Javelin headers there are some professional services I will avail myself of regarding photo analysis for some final conclusions.

In the mean, if you examine tthe photos you just reposted it is evident that some recognizable features appear.

First, the reason behind the longer manifold bolts. When looking at the bolt flanges, evident are the original flange face that has been extended. The original line that would represent the original  bolt head flat surface is evident when looking at the slight indentation approximately 5/8ths inch out from the head exhaust surface. The line that defines this original stock dimension is evident from the top view in pics number 2 and 3 above at the bottom of both photos.there is a shadow that is perpendicular to the attachment bolt plane at the indicated dimension out from the manifold to head parting line as well as a visible taper or indentation on the outside line which coincides with the longitudinal surfaces that form the outer diameter of the manifold where the bolts go through.

Later I'll send a Flickr copy of these photos with circles to indicate what I'm describing.

The question is, how is it evident these are modified versus clean sheet castings? More later with graphic references.

Oh, well yes these are the subject of my research, however I thought you were referring to the Penske Javelin also as having some slightly different aspects to the flange.
