if i were you i wouldnt bother with those heads. Those are FRPPs CNC 3 valve heads, and sutton did some dyno testing of those in a thread round here somewhere, but the results were not so good. they didnt gain much HP at all, u would be better off waiting for heads from Sutton/Livernois/Fox lake. and they take whatever 3v cams u want, stock or otherwise. Brenspeed sells comp cams stage 3 ones, that picked up like 35hp or more with just bolt ons. RPM sells the full comp cams lineup, as well as crane's and crower's cams
I agree. The porting package from livernois includes larger valve seats
and valves plus the port clean up. Their heads make about double the
FRPP heads do.
