Exhaust flange gasket recommendations
When I first switched my '63 Bonneville (389) back to duals (stainless) in '86, I had a real Dickens of a time getting the pipes and the flanges to line up squarely.
More recently, the engine was rebuilt and everything put back together (not by me). I have a noticeable leak on (I think) the passenger side, and it sounds like it's right up front. The likeliest culprit is the flange. What is everyone using these days for good sealing? Extra thick gaskets? Brands? TIA

Yes, Remflex gaskets are 100% the way to go for the manifold flange against the cylinder head. They're thick and compress to form a very good seal. They have to be handled a little delicately during installation, though. Don't want to bend them.

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.
