I have water in my oil and am pretty sure that I blew a head gasket even though the heads are o-ringed. I have dished out pistons and like 8 to 8 compression. So I was thinking about milling out my heads a lil; I have edelbrocks with huge 62 cc combustion cambers. I was thinking about 60 to 58 cc with 12 to 14 psi of boost. How much do u think I will have to take off to get rid of the groves cut into the heads. And what headgaskets go u guy reccommend for blown apps. Anyone no where I can send my heads to get them cnc ported? And one last question I haven't done my compression check yet is there any other possible sorces of water other than headgasket?
