Default Changing setup, again, need opinions.

I am thinking about going ahead and doing heads. I was looking at the stage2 patriot ls6. What CC chamber should I go with? I would like to stay as close to the stock compression ratio as possible.
Here is the cam profil
230/236 595/586 112lsa
90/90 Fast,36lb inj, kooks race headers with dual elec cutouts, The usual boltons.

mill to 59cc, try to get as close to 11:1 cr. thats optimum for the LSx motors. However you have to be careful about PTV clearance. Research baby!

Fitting your criteria for CC, I say give Gunnar a call and get those on a 64-65 cc with 2.02/1.57. The 6.0 gasket used is a bit thicker than your stock gasket.
Gonna have to measure PTV.

Other option is a stage 1 243 PP

My M6 C5 vert runs 230/236 .595/.610 112 lsa XE-R cam with PRC 2.5's, Dynatech LT's, Ported FAST LSX/LS2 TB and all the bolt-ons. Pretty close to your setup.

The heades are 62cc with stock graphite gaskets..Bad luck with Cometics.

Work done by ProStreet MotorSports in Md. (Phil99vette). Phil's speed density tune makes this baby purr.
