well the stock ls2 with the 600 lift cam made 504hp(+-), 463lb.'s(+-) after intake and heads it was 550hp 450lb.'s something similar 2 that id say they loved it for 1,000 dollas of heads and 400 for an intake

These 3 dyno thrash articles have provided a real host of knowledge. Lots of info. All have used the exact same stage II cam, so they're comparable for the most part.
Cam specs: 232/236 @ .050, .600 lift on a 112° LSA
Stock LS2 head:
502.3 hp at 6,300 rpm
465.3 lb-ft of torque at 5,100 rpm
65cc combustion chamber
Livernois Stage I head:
520.3 hp at 6,300 rpm
467.7 lb-ft at 5,100 rpm
65cc combustion chamber
AFR 205cc LS2 head:
547.1 hp at 6,400 rpm
479.5 lb-ft at 5,500 rpm
66cc combustion chamber
Dart Pro 1 225cc head:
532.5 hp at 6,700 rpm
478.4 lb-ft at 5,200 rpm
63cc combustion chamber
Edelbrock Lingenfelter Edition LS1 head:
535.9 hp at 6,700 rpm
479.6 lb-ft at 4,900 rpm
65cc combustion chamber
Livernois LS2 Stage III CNC head:
544.8 hp at 6,700 rpm
483.3 lb-ft at 5,300 rpm
65cc combustion chamber
TFS CNC LS2 head:
552.0 hp at 6,500 rpm
486.9 lb-ft at 5,100 rpm
64cc combustion chamber
L92 head with L76 intake:
546.8 hp at 6,500 rpm
494.9 lb-ft at 5,000 rpm
70cc combustion chamber
L92 head with carb intake:
545.8 hp at 6,900 rpm
453.8 lb-ft at 5,200 rpm
70cc combustion chamber
Good info. Those L92 heads with the L76 look good.

That cam(from Russell's post) is nowhere near ideal for the L92 heads, relative to how it is for the cathedral style heads. With better valve timing, the L92 heads would walk away from the rest of the pack...even with a cam that is similiar duration. The L92 heads with the intake on flows damn near what the other heads flow with no intake. Flow numbers are not everything, but they are a large part of the picture. These heads and the L76 intake combo will take a vastly different cam to make good power. Not necessarily a larger cam, but a better suited cam.
The 70cc chamber is also making it run very low compression(relatively speaking). These heads are going to make HUGE power once people start playing with combos and port work.
