looking at one of the pictures of the intake runner and valve, it almost looks like they killed the swirl capability. <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />

I sort of agree, its hard to tell for sure if swirl ramp is there at all. I think swirl is first to go on a lot of stage 2 and more heads.
Programming would be pretty different for hi flow head with next to no swirl. I guess if flow was high enough power would be good but your low speed torque and throttle response would be down.
