Dart 360 head H.P. limmit?

We are running a new centrey block 10,200 , 500 inch, Dart 360 heads, 206D screw blower 50% over, 44 amp mag, base compression is 12.1 to 1, the intakes flow right at 370 We run it very safe at 6.20's to 6.30's, at 40 PSI boast, no cad off the plugs, My question is how hard can I push this set up. Has anyone run a set up like this on the track or a dyno to see how much HP you can make with conventional heads ?
max boast in psi?
max H.P.?

Any info would be greatly appreciated

Thanks

Butch

 

360 Head combo

Have the heads had any port work done to them? 370 CFM seems a little low for a runner that size.
