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?

Head gaskets. But hell might as well sale those and buy others if you pull them lol

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.

i want some more PTV clearance to run a different cam I have the 228R now but I want something with more lift and duration and would even like to bump it up to 62cc or even 60cc if that will give me enought clearance

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.

Just put some patriot stage 2 59cc's on my cam only 224/230 comp and it was a huge difference. Went with LS6 intake too, couldn't be happier wig car. Love the bump in compression, .076 clearance on intake side..
