58cc head, how thick is your gasket, what bore is the gasket, and finally, what is the cc of the piston?

If you have MS excel you can download a CR calculator from my website.

If you don't have excel it won't work.

How have you lightened the car?

Be sure to get the C&L cal'd for the injector/EEC/MAS (the black sensor) combo you are using.
I have some C&L stuff on my site as well.

I have no idea how to estimate your power level.

good luck

You should be in the 9-9.5:1 range. No way to be exact w/o measuring.
