I have a 65 gto which had a engine swap to a 400cid from a 76 firebird, it does not have headers now. I have the fenders and hood off and was thinking about putting on some headers. Does anyone have any idea if there are any that would fit? I am a bit afraid of what I read in catalogs as they usally state only fit if engine came as an option(which a 400 was not a option that year)
