Best way to reduce compression ratio?

Ink, thanks for the info! Not to be an ingrate, but what do you think of those who say that installing a thicker head gasket decreases quench, which only leads to more detonation?

Has anybody reduced their compression this way? Please give the details.

Are there any other cylinder heads that I should consider that might reduce the C.R. while still being efficient?

Very good probability....perhaps a cam swap to bleed some of the compression is more in order....
