exhaust port shape?
hey guys,
i'm just wondering if theres a way (without pulling the exhaust manifolds right now) to determine what shape my exhaust ports are. reason being, is the parts guy gave me gaskets for round ports. and i honestly don't know what i have on my '69 307. so. i'm just wondering if any of you might have an idea off the top of your heads?? thanks! -Sam.

Bob,
Thank you!! now i don't have to wait before i take them back! i didn't think they were round, but for 40 bucks for the gaskets, he was more than willing to sell them to me. thanks so much. ![]() -Sam.

Re: exhaust port shape?
get a set of fel pro there half the cost at least and the best made for manifolds. run the engine for a day then re tighten them up again. use lock washers too grade 8

Re: exhaust port shape?
i'll definitely request fel-pro's then.
and don't worry. i've heard too many horror stories about people not tightening their exhaust bolts up. i'll be sure to make it a weekly thing after the intial tightening. thanks again! they're going back next week. hahaha.
