Ed, I would go really big on the cam. Even with stock heads a big cam really works well in the upper rpms. Mopar 3.0 ran a bone stock head with his custom intake and said he had great power up there.
I would guess your cam is milder then the Crower RPW stage 2 clone.
Yeah, it is fairly mild. Are you thinking E-27829? or F-5365? On the solid or hydraulic lifters?

And I wonder how maximized your timing map is from what Sundance 6g72 has said. I would ramp that timing up progressively at 5500 6000 6500 and 7000 unless you feel you have a perfect tune. So you don't worry so much about hurting the motor, my first turbo setup I accidentally ran 24 degrees of base timing (so about 50 degrees total advance at WOT and high rpms) and even on 5 pounds of boost and 92 octane it was fine because it was crazy rich. At 10psi it went boom with all that timing and the fact that it leaned out to 12 and 13 to one.
You are NOT going to hurt it if you even get to high 40's in timing up top if you are running premium. HP should be low enough that you can recognize knock with some microphone setups and tone it down.
Right now I have been running 87 octane. The spark map is probably not maximized, but I was planning on doing that during some dyno time...
