Max Compression With Felpro Gaskets??

1wild&crazyguy said
I know the 8553'SP'will hold 12.5, don't know about the 519.

Tech at Jegs told me about a Mr Gasket composite #3211G that would work fine for tons of compression and nitrous or even super chargers.

The 3211G is only .040 thick and wont work for me.

How thick is the 8553?? And where do you get it? Is that a felpro#?
