I’m really curious now if there is something I could do? New piston and keep the cam. Or new pistons heads and cam. Or pistons and heads. I really would love to hear what you guys think. It’s not looking like a gasket would work and honestly I don’t feel comfortable even if it would work.

A gasket will not work all that well unless you are really on top of the tune. Most aren't. Swap to a different piston and keep your cam, it is a nice cam. Fix the root problem not the symptom. J.Rob
