Right now im running edelbrock performers with 60cc combustion chambers. Im looking into some Afr 185s and see they are only offered in 58cc combustion chambers. Right now my compression is 9.25:1 how much would that raise it, ballpark?
 
Not a whole lot really. There are compression calculators that you can find just using google. You need to know your piston and head gasket specs, though.

Used a compression calculator online. Says currently my ratio is 9.27:1. With a 58cc chamber instead of 60cc it raises it to 9.4 something to 1. However by adding a .050 inch thick headgasket it lowers it back down to 9.26:1. Thanks for the tip on the calculator thing!
