390 w/open chamber heads

Don't think I'd pop for a forged steel crank with the kind of usage you're talking about. I go with a SCAT 9000 series crank myself. http://www.summitracing.com/parts/sca-936020/overview/ much less $.
The 596 heads would be my pick, with 2.02/1.6 valves. Have the bowls cut and blended for the bigger intake valve. The Performer with a proper port match will do OK, but a Performer RPM would definitely make more power. I don't think the RPM will fit the AC compressor you have in the pics though.
Don't go over board with the compression, 9.5 tops. Might want to talk to Mike at MRL, get you set up with a rotating kit.
