Need Help with Hedders
I have a 1971 Lemans with a Chevy 350 with Square port heads. I didn't realize there were so many differences in chevy headers and inadvetantly bought flowtech headers that are oval port and leak at the gasket, including a copper gasket. I am considering doubling up onthe copper gaskets, a sqare port against the head and a round port against the header flange and see what happens.
I need advice on either how to seal the gasket leak OR the obvious, what part number to do I need to use to find a set of square port chevy headers that are designed for a "chevelle" with factory a/c. Thanks for any quidance, without flames! Bill [email protected] |

Fel-Pro #1426 (IIRC) will seal almost all round port headers up 1 3/4 dia. to stock SBC exhausts.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
