Im looking to sell my stock ls6 heads and get the PRC stage 1's.

I would mill them but i dont know how to!?!? Im im sure nobody here in my shop knows how to either. If i just mill them down to 62cc would i be fine?

Anyways i hope for 420-430rwhp with the setup and 11's would be great too!

So....what HP/TQ do you think i should get with this??

Mods are:
MTI lid
P&P TB
SLP MAF
LS6 Intake
PRC LS6 Stage 1 heads
G5X4 cam
ASP pulley
Pacesetter LT's w/ ORY
Hooker Catback
M6 with 4.10's

Would this be a solid 420+RWHP combo?

If you ONLY GET 420 SHOOT your tuner. 450 at least.
