I'd like to bump my compression up a bit when I swap my ported heads on, but I'd have to shave the heads a ton for even a slight gain in compression. I remember reading a magazine article where they installed a head gasket with a compressed thickness of only .015". If I could get a head gasket of that thickness for my engine, it would shave around 8ccs off my combustion chamber volume, and also bring the quench down to around .055" (I'm pretty sure the pistons I'm running are around -.030 deck height). This would put me up to around 8.5:1 compression instead of the miserable 8:1 I'm running right now. Not much of a gain, but better than none at all.
So back to my question; does anyone make a thin head gasket for the 460? Also, is there any disadvantage to running a thinner head gasket?
