I am using the Superformance gaskets which don't come with the end seals which is why I am looking for them. And I have used silicone before and it worked okay, I would just prefer to use the foam for this build.

The craft store foam is an interesting idea. As long as it doesn't become oil soaked or fall apart, it would be worth trying.

Coyotes and Darts. Yeah, we get around.
