Hi everyone, Chevy admirer from afar. Im a Buick guy. Last year I bought a 73 corvette that came with a set of NOS new in box Blackjack headers. I have since sold the car but still have these headers. This thread is the most informative on the internet in my searching so thought I would try and revive it.
A few things I notice compared to other pics. A lot of NOS headers have made in Mexico on the AK5000 tag. These just have Mr. Gasket California. I dont see a part number on the headers that match the above catalog, just number 95822 on the box. The alumacoat is thick and could be hiding it. Did Mr. Gasket acquire blackjack later on? Any idea what these headers are for? They are 1 3/4 primaries and 3 collectors.
Thanks for your help!
Louie
