I'm wondering if your car will pass the smog check with your current heads. Just get the E.O. decal for the regular performer heads. Are the AFR 185's emissions legal? If they are they would seem to be a better choice since you already know your 2.02/1.90 valves are clearing the pistons and you have the stud mount rockers from the edelbrock heads.

The combustion chamber volumes will determine you compression ratio. I think the edelbrocks you're using are 60 cc so use that as a reference (if they haven't been milled). Going with the smaller chambered 58 cc will give you some more power but at the expense of having to run higher octane fuel. What's the lowest octane you can run now without detonation?
