its a 467, 310 speed master heads, 713 lunati voodoo hr cam and most likely a 66 tripower. i gurss i dont k ow how racey this will be, i plan to run 3" exhaust tail pipes included. this motor is using mahle 6.5 cc pistons .020 in the hole with 78cc heads. i plan to run cometic .027 gaskets to get it close to 11.0 cr and hope for the best on pump gas. im hoping to make a good honest 500hp or more with the tripower with the option of swapping to a single 4 for a touch more

1 3/4" sounds good. Maybe the next size 1 7/8". Not 2".

I checked their website and was unable to find any listing for a traditional Pontiac engine just Chevy stuff.

Well I'm confused! Their site says SBC/BBC in several locations. To me that indicates they're conversion headers for Chevrolet installations. Not to mention they claim the same header fits Oldsmobile 442's.

Has anyone called and asked them?

Pontiac GTO 1 3/4" Longtube Headers
1964-1972 SBC/BBC (5.3L-7.4L)

EDIT:

I think they are Pontiac headers on further looking.

Round port headers.
