Help Me Pick New Heads/Cam for 383

[Spot1984]

Well I got a 383...Here is the specs:

Crank- 4340 Forged Steel Crank
Rods- H Beam 4340 Rods 6.00 inch
Pistons- Keith Black Icon Forged Pistons Flat Top with Two Valve Reliefs(+4.90cc Head volume) 4.030 Bore
Cam- Comp Xtreme Energy Hydraullic Roller( Intake @ .050 248/Exhaust @ .050 254) Intake lift .562/Exhaust lift .580, Lobe seperation 110
Heads- Be nice, I got WAY cheap on heads (ran out of money) Aluminum ProComp 64cc Combustion Chambers, 210 cc Runners/ 2.02 Intake, 1.6 exhaust
Rockers-Roller Shaft mounted Rocker System by RPM 1.5 Ratio
Valve Springs- Isky(Dual Spring) 275 lbs/inch
Carb-Holley 750 Street HP
Intake-Hurricane Single Plane 3000-7500 RPM

I want to spray at least 150 shot of NOS and this thing will be street/strip. I am not too concerned with how street friendly it is

I am currently looking at AFR SBC Competition 227cc Heads:
SB-Chevy Competition Cylinder Head
227cc Intake Ports
Standard Port Exhaust
Angled Plug Type
65cc Combustion Chambers
80cc Exhaust Ports
1.550'' Roller Valve Spring
225 lbs. Seat Pressure
.710'' Max Lift

I would like to grow into the heads. I'm not sure if the cam I currently have is up to the task of how much these heads flow. I appreciate the help fellas!
