can i use the heads i have...
can i use the heads i have... for a pro charger. there the 59cc ls6 style patriot performance heads. id like to buy a supercharger but cant swing another 2grand to buy another set of heads. would the car run shitty? or any other issues?
what does that put your CR to?
sounds like it would be high which isnt good, you'll have to run more octane.
could you sell or trad your heads.
you could sell them and then buy some 6.0 heads which would help you more, and use the extra $$ to fund the supercharger.

Those heads are more harm than good from a overall tuning standpoint. Your 2000 Vette stock was 10.1:1. That was with 67cc heads. Now you have 59cc heads. You are at 11:1 now or just under. You want reduced compression not increased. I would sell those heads or see if you can trade them in.
I am running ported 6.0 heads that are 69cc's after a cleanup .010 decking.

Yea, I wouldn't mess with high compression and boost.......
I made 6psi with 10.6:1 compression on my stock motor.......popped a head gasket....I think that hurt the ringlands pretty bad, motor had a ton of blow by after that.....
I then put some 73cc chamber heads on it and it dropped me to around 9.5:1 comp....then I was at 4psi......
Your A LOT safer with lower comp and boost.....unless you want to put the motor in an early grave.....
