Whats up pal. If you run this setup you should get aprox 8.73:1 CR

Bore diameter: 4"
Stroke: 4"
Combustion Chamber: 66cc
Head Gasket Thickness: .05"
Head Gasket Bore: 4.03"
Piston to deck clearance: 0
Dish: 30cc

Hope it helps

8.7:1 is too low IMO for a S/C setup. I would run something in the range of 9.2:1 to 9.4:1. -22cc pistons with 66cc heads and 0.054" gaskets will get you to 9.3:1.
