rectangular port 427 heads, header question
my buddy brought his 69 camaro over for me to put headers on it. The headers are for oval ports as well as the gaskets..will these work? Sorry, ive never really messed with big blocks so i need to know what he needs as far as headers. I would figure they make a header for the rect port, but i dont know. Ive searched and searched google and havent reallly came up with anything. It had some square port gaskets on it with oval port headers and it was leaking like crazy. I dont know if it was because the headers were warped or what. Will these new oval port headers seal with the right gaksets, or does he need to send them back for different ones? I put the gaskets up to one another and It doesnt look like it would seal very good but i dont know. Thanks

Oval & Rectangular ports refer to the intake ports not the exhaust ports but there are different headers that take different gaskets.From what i remember there are D shape ,oval & square header gaskets you just have to match the headers ports to the gasket.The intake is the only thing you worry about to match oval port or rectangular heads.

It's possible someone could have hogged out the exhaust ports.Try the round gaskets if not he may have to get different headers.Hooker supercomp headers are good they come in different sizes.
