Will I got a set of the Dart 1 alum.heads good to 700 lift, 215 cc intake runners, angled plug and 72cc's. From what I get 350 blocks are stronger than 400 so I am looking at getting a 383 from a 350 block. Any ideas on a combo? I found this one which brings me close.

Combo 15 uses a 383 cu. in. engine with 9.5:1 compression and a 750 double pumper. With a 280° hydraulic camshaft and the AFR 190cc Street heads, this combination makes an awesome 471 HP and an incredible 515 ft-lbs of torque. This is the ultimate street engine.

Displacement: 383 cu. in.
Carburetor: Holley 750 double pumper
Heads: Air Flow Research 190cc Street
Intake: Air Flow Research FloPower RPM
Camshaft: Comp Cams 280° Magnum hydraulic, with 280° of duration, 230° of duration @ 0.050 in. lift, and 0.480 in. lift
Headers: 1 3/4 in.
Distributor: MSD
Timing: 34°
Comp. Ratio: 9.5:1

MAX HP: 471 @ 5500
MAX Torque: 515 @ 4500

I have the Dart heads , 1 3/4" headers , all msd ignition from dist. to 6al box. I have a 280 H comp cam complete kit and a complete nitrous "cheater" system good to 250 extra hp. What can I move around to get full use of the heads?
