Compression Question

[Slice]

Almost finished with 500 stroker 6 pack build. I'm trying to decide what compression ratio to go with. The heads are eddy rpm's, the cam duration is .231/.239. From what I understand felpro gaskets can put me at 10.4:1 or 10.1:1.

Can someone tell me how much difference this will make and how risky it is running 10.4:1 with my setup??? It is mostly a street car and though I want power, I don't want to worry about overheating or detonation.

Sorry for redundant post, don't know how to delete it, but if you haven't seen it and have a response, please do..
