Mill Heads or Thinner Gasket?

What's better? Milling my 823 heads .020" for ~65cc chamber, or running thinner head gaskets?

What thinner head gaskets are people using?

Thanks guys!

Is this going into your 6.0?
If so where do you wanna be in compression?

By milling to 65cc's and a stock .051 gm mls gasket I think you'll be at 11.2ish.

Yep going into a 4.005" bore 6.0 with flat tops. I'd like to be ~11.5 and i'll be running nitrous

both.,
or run as tight as quench as possible.with gaskets and out the bore measurement. i aim for .035-.040 quench on any build.
example:
piston out the bore .015
gm .051 compressed gasket
= .041 quench
