When we inspected this car at MCACN in 2022 we found blue paint in the trunk that had transferred from the headers to the trunk floor,likely while in transit. The paint matched the headers,sio we safely concluded these were the factory supplied headers,shipped with the car.
The original exhaust manifolds were there as well, in pristine condition with about 15 inches of exhaust header pipe attached. Probably removed on day 2.

Photos of the original exhaust manifolds including the heat riser and head pipe cut offs that were in the trunk when we inspected the car. They were likely delivery date take offs as the they showed no signs of any wear, dis-coloring or carbon accumulation. Note the original white-asbestos donut and (correct) clocking of the heat riser valve. I may have photos of the installed headers, will have a look.

Great photos in this thread! Of particular interest to me are the 67 Camaros pics especially the one’s shining light on the “67 Z28 mysteries (to me)”.

RPO Z284; would be header/cowl plenum equipped from the factory.

Z28 with ECL BA= Z28 without either.
Z28 with ECL BB= air plenum only
Z28 with ECL BC= headers only
Z28 with ECL BD= headers and cowl plenum(refer to window sticker pictured)

There were 4 Z28 ECL combination as represented above.
