318 combos?

My 318 that I'm in the middle of building consists of:

-factory shortblock that was bored .060 over with stock cast pistons about .060 down in the hole...LOL (again, it was a stock rebuild by the previous owner)
-RHS heads with a 62cc chamber and 202/160 valves to bring the compression to about 8.9to1
-hughes 1.5 roller rockers,
-edelbrock performer RPM manifold
-edelbrock performer RPM cam & lifters 234/244 dur @.050 488/510 lift (not the best cam but using what I have)
-holley 600 spreadbore carb
-comp cams double roller timing chain with a chain tensioner and a MP windage tray and MP viscous fan
-Dougs headers with 2 1/2" exhaust with flowmaster mufflers

the limiting factor on my engine is of course my lousy compression, and the lazily ground edelbrock cam....id be happy to get about 325 horsepower out of it...what do you guys think?
