are your heads milled? if not you should have no issues at all.. there are people on here with milled heads and doing the 236+ duration and .600 lift with out PTV issues..
I was thinking about going with some 1.8rr on my Hotcam. Would be a little bit more lift. It would go from a .525 to a .556....and maybe throwing an underdrive pulley, just to see what the gains are......
