At what power level would you guys recommend upgrading to supertech oversized +1 in +2 exh valves on a p12 head? I just sent my p12 head to maxworx to get their stage 0 head work done and was thinking if i should slap on oversized valves. Im aiming for around 500-600hp at around 25-30psi of boost. Head is going to have supertech 93lb dual valve springs amd tomei cam gears, thats pretty much it as far as the head goes.
