are there differant heads i can upgrade too and if so any idea how much it would cost? im looking for about a 10.0:1cr. anyone?

 

stock you have at least that..... so no would be the answer, unless you want to swap some phaze II 2.2 heads on, but youde hafta run race gas or have some sort of managment so you could pull timing, it would bump the comp ratio to about 11.5:1

Aren't the RS heads already at 10.0:1?

At least the 00-01 RS's are.
