Ya I may have to break down and just do the RTV thing. But I plan on taking this all back apart soon, and Id rather not have a mess to clean up.

But I did take some measurements. On my manifolds, the outlet is 1 7/8" ID, and 3 1/2" bolt spacing. The gaskets i found that are supposed to fit have a 2 3/8" ID, and 4" bolt spacing. Very far off.

More than just finding the gaskets, Im now wondering if manifolds with the much larger outlet diameter are something I can find and replace mine with? Anybody know whats what?
