    And the general rule of thumb is .007=1cc. So if heads are 70cc, then .030 would net you right under 66cc heads. I would go with .030 and a thinner gasket to get your compression up to 11:1, or .030 or a stock gasket to get 10.7. This is assuming you run the flat top LQ9 pistons and running 91-93 octane.
