Running LS9 heads on LS2
Had anyone made this move yet? Curious what the final compression ratio will be. Do you fell its worth the 900.00 price tag and what kind of gains will be acquired from this mod?

I made the move. 9.6 CR. It was the logical move for me due to the fact that my CR was previously at 11.3 with a set of milled 62 cc AFR 205s, and they left me with too much compression for my set up. Wound up with some valve damage and flipped to the LS3 heads. Car runs great, but I had to run a smaller pulley to get back some of the low end performance.

Stock bottom end. Running meth and a conservative tune @ 11 psi.
