I have a g5x3 cam and some stock ls6 heads, since my heads are gonna be off soon I'm thinking of sending them to precision performance in florida or west coast cylinder heads.
any way I want the stage 3 port and polish and I want them milled to 59cc to raise my compression up a bit. I already know I'm gonna have to flycut but I'm prepared to do that. the motor is out so it shoudnt be that hard.

what kind of power would this make with the mods I already have?

I'm tryin to get to around 450-460 rwhp.

the shops seem pretty reputable.


has anybody had anyexpeience with these shops?

anyway thanks for the feedback guys

450 - 460 is very possible.

 

It all depends on how your heads come out. A FAST 90mm intake would definitely help you out bigtime

 

Perhaps!

 

I would send the heads to TEA or ET myself.
