Yeah, I bet a restrictive valve could kill velocity down quite a bit, as well as change the TIMING of the pressure variations on the intake manifold side of the valve. I'm gonna theorize that a restrictive intake valve would somewhat attenuate and delay the vacuum/pressure effects on the intake-side of the port, as it would limit the cylinder's ability to affect anything past the valve. Sort of a smoothing effect, in other words.

Exactly 610 posts on old board, first whacked post in the history of this one! Funny moparts quote from Waginator: "*If you want your package lost, like bermuda triangle lost, use DHL (formerly airborne) *if you want it to get there but destroyed, use UPS."
