The stock HG is 1.37mm. The thicker the head gasket the lower the compression ratio... not necessarily a desirable thing on a N/A.

More materials....

and no... that would be blindly increasing the compression ratio. Granting you a very small bump in power and a nice large bump in risk of detonation. If you want it to be reliable, you want to go with the stock HG thickness + whatever was milled off when the head and block were machined. It's not worth the minimal gain, IMHO.
