Header fitment on 75' grand lemans

[Karnawgie]

Looking to get rid of the y pipe on my lemans and get some duals going. My go to idea was get some headers and some straight pipe and call it a day but pontiac headers seem a little more difficult to work with than some old chevy headers.

A local person has a few sets of headers for earlier model gtos. I assume the flanges would line up to my 350, but does anyone have any experience or guesses if most or any style headers for a gto would fit my 75 lemans? Thanks.

If I can't be sure, I'll figure out a way to use my stock manifolds and make an exhaust.

Summit Racing lists headers that are supposed to fit.
Earlier GTO? If they fit a 73 they should fit yours. Earlier than that different body style so you will have to determine if they fit.

Yeah idk what year but I suspect a 3rd gen gto, 60s. Body style chassis interference and all that is the worry.

That's 1st generation 64 to 67 or 2nd 68 to 72.
