Already max out my 2560 (currently I have it at 17psi)

GT2560r -> EFR 6758 maybe? :party:

14psi? I thought those top out at like 18? It will probably taper but I'm sure you could squeeze out more midrange.

Next question I have with how thick head gasket should I choose? Cometic seems to have multiple thickness HG's for 1.6 engine: 0.027, 0.030, 0.036 and so on...

I will use 10.6 pistons.

Do not use anything thicker or thinner than OEM. Period.
