The Felpro 1016 gasket has a 4.3 gasket diameter , with. 039 crushed, and my #13s measured 78cc, putting the compression at 9.46. Talking with my engine builder we decided to ceramic coat the pistons top, to help prevent damaging the pistons should I get a tank of not so good 91/93 gas. Do ceramic coating really help against detonation damage? And how many builders are actually using ceramic coating?

Tools, but here goes. Your calculated STATIC CR of 9.46 will most likely be at around 8.5 DYNAMIC. ( running).
This should be perfect for even 89 octane depending on your timing and fuel adjustment. Sounds like a good build even without the ceramic.
