Ron and/or panic, according to Ron's numbers; wouldn't then a larger exhaust valve than a 1.60 be more beneficial above .500" lift? or am i missing something here in oversimplification? i'd gladly trade off a little intake valve diameter to pick up a little more exhaust flow. i planned on using pontiac 455 1.66" exhausts with a 350 pontiac 1.96" intake cut down to 1.94"
