Those are some nice heads, no core charge so I am in with them when I am ready. .500 lift 350cfm on the stage 2 heads. I want to see the numbers on the bigger valve heads. I am in the learning curve and a Newbee on this stuff but I will get the hang of it.

Well the small ones flow 408cfm the next bigger flow 420cfm and I am sure the big bad boys will flow 440-450cfm+ on a 4.125 bore I intend to run. Should make a bad *** monster for sure since indy clames their gen2 hemi heads big valve flow 480 @.800 lift. This neegen is an animal waiting to be born.
