[QUOTE="Dynotune04, post: 7605908, member: 52373"] the reason i asked about the ported heads was because factory two valve heads have a nub in the comustion chamber that helps with emissions and what not. but that nub also gets hot and will cause detonation on a high boost aplication. when most companies port the heads they take the nub out of the cumbustion chamber. 20 psi on 9:1 is a fair amount but i dont think it should be an issue with pump gas. how much timing is in it would be the key factor here.
