I don't know how much of their experience comes from working w/ lower-lift Stocker heads, but cylinder head guys like Darin Morgan and Chad Speier emphasize port designs that remain stable w/o any backing up in flow at lifts well above the actual valve lift used, even if it reduces some of the flow #s seen at lower lifts.

However, those recommendations are when they're talking about ports remaining stable to 1.0" when the valve lift might be .700". They're saying this, IIRC, based on findings from flow testing well above the standard 28" H2O pressure since the higher test depressions can reveal different flow behavior than seen at 28". How that might need to be "adjusted" (as much as can be w/in the constraints of the class guidelines) when the peak lift is .400"-.500", I dunno... just throwing that out there for consideration. Thx
