NOS header flanges from Douglass Muffler Mfg as used on the factory supplied Z-28 headers in '67. These are owned by Robert Lodewyk and are the 1.75" round port style.
I also have this original 1968 Z/28 raced in Stock, Super Stock, and Modified Production from 1971-1975 out of NJ. This has a set of Stahl adjustable collector headers on it. He brought the car to Stahl and had the headers made up.I'll get better pictures later. These are the best that I have for now.[/quotelove the turnbuckle on the drivers side
Yes, sometimes you'll see some strange and/or funny tubing bends on headers that are trying to haveequal length. I can't think of too many crazier looking bends than on the Stingray headers shown belowin 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 beenreplaced 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.
