97blackgt said:hey snakebit what kind of gains can be had with ported and polished PI heads with regular PI cams and intake on an almost stock engine? How much more power will ported and polished PI heads add over the non ported Pi heads?
You can gain 20rwhp from a good port on those PI heads with the stock PI cams, and another 20 or MORE with a nice set of cams. On PI heads over non PI heads I think the gains are around 30hp
