440 Build Head and Cam Selection?

So I sold the small block and I'm in the process of building my 440.:D
The car will be mostly street with some occasional passes down the track. I'm looking for around 500 hp.
I would like the car to have a lopey idle with low end to mid range power.
Do you guys have any input on heads or cam selection for my build?
Performer RPM heads are too steep for me. Anyone running the Source 440 stealth heads?

Here is the plan for now:
1972 Duster
4 Speed
1968 440 .030
L2355 Pistons
10.1 Cr
Iron 516 or Stealth Heads (I own the 516 heads but they will need a rebuild and I would put the bigger exhaust valves)
Stock Rockers
Lunati Voodoo Cam 10230703 (60303) or 10230704 (60304) I want stay hydraulic flat tappet
RPM Performer Intake
800 AVS Edelbrock Thunder Carb
TTI 2" Headers and TTI 3" Exhaust
3.23 8-3/4 rear. Gear could change in the future.
