Reply to "Do our intake gaskets ever really seal ???"

Here is the photo. I can now see that there is a problem with alignment of the gasket bolt holes. The misaligned bolt holes in the gasket are shifting it to one side of the intake runners and thus reducing the amount of gasket one side of the runner and covering the opening on the other side. This has not been on my radar screen and may have been working against me all along. A misaligned gasket on top of a serrated surface on the manifold is asking for leaks. Hence the reason I asked "Do our intake gaskets ever really seal?".

This is a Felpro 1228 gasket. It needs the bolt holes elongated on one side for it to work. My new Tim Meyer gaskets have bolt hole alignment issues as well.

It looks like each time we install a manifold we need to check alignment of gasket's bolt holes and intake runners on both the manifold and the heads.

Doug, what else do you see in the photo? Thanks!
