59cc heads???

This may be a dumb question but I have prc stage 2.5 heads that were milled to 59cc by the past owner is there a way to increase the cc without swapping the heads again?

You can change head gaskets or sell them and replace them because a head gasket can only get you so far. It depends how much cc you want back.

Flycut the pistons, that is the correct wayto do it. You do not wat thicker than stock gasket bcause of quench and increasing it would make the motor prawn to detonation and knock retard.

You could gain 3cc with decent flycuts and also more ptv clarance.
