Ported Heads 
Re: Ported Heads I've seen those too.
Unless the guy can give you Port Vol and a Flow table don't buy them, just go with a know quantity like what the sponsors give you.
Anyways I would want all of that stuff for $2700!

Re: Ported Heads 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" />

Re: Ported Heads 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.
