I have to agree here. If your completely in the dark on this stuff right now, then the stickies are perfect for you. there is a ton of very important information in them.

Once your schooled on them some you'll know more of what your wanting parts wise. It's ok to not know, we were all at that point at some time. Just reading & research along with hand on stuff is the only way to learn.

k so i read it...and i looked on the ws6 store and looked at stage 2 patriot heads..they have a table showing lift, exhaust and intake when the lift goes up the flow goes up with it meaning more comes into the intake and more exits the exhaust valve correct? whats is cfm? cubic feet.....i dunno thanx guys.

The CFM is the rating for air movement in cubic feet per minute through the head. You want to pick your heads to go with your cam selection.

For example, if you have a cam with .600" lift then you would want heads that flow very well up to & maybe a little past .600". You wouldn't want a head that shows flow dropping off after say .580" lift cause you won't see your full potiential of the cam.
