Trick Flow 440 heads, The Real Deal?

I dyno tested the Trick Flow intake today on my 470 low deck engine. With a Quick Fuel 1050 carb the engine made 690 hp @ 6500 rpm and 610 ft-lbs @ 5500 rpm. Seemed to be a really strong combination. It certainly made more power than any of the other intakes I had tried on this engine.
