9:1 Piston & Head Gasket?

[4wd-Eclipse]

Soon I'm going to overhauling the engine and using 9:1 JE piston. So I need to know if a thicker metal head gasket should be used with this compression ratio for daily driven 1G dsm with 15 psi low & 22 psi high (for racing only) using 94 octane fuel.

Use a stock HG if that is all yoru going to run. I ran 24psi constant on a stock motor with no lift/heating/pressurizing or anything... Im not sure which is the point when it really becomes an issue, but I dont think 22psi is it...
