Now w a set of TEA stage 2 243's whats the HP gain ya think Im looking at w them CNC Porting my heads and bumping the CR up to the most I can w Pump Gas?

Also would I be leaving Power on the table keeping my Cam or swap it out at the same time as well?

I'd run a .040" head gasket and that should put you at 11.2 SCR a Fast intake would help that thing breathe in the upper rpms as well with that healthy cam.

i agree greatly with going to a fast 102. my set-up is pretty similar i make 453rwhp with a smaller cam and a fast102. i will have 510 race engineering port my heads and mill them to raise comp ratio.

A fast 102 and a set of trick flow 225's would put you in the 475 rwhp range
