Trick Flow 440 heads, The Real Deal?

AndyF, could you post the specs of that engine? I've got a 400 and looking to build a stroker, but want some longevity.

400 block with 3.91 crank, 6.700 rods and Diamond dish pistons. TF heads, Ultradyne solid roller cam (259/.650 lift), Mopar M1 intake, 1050 Dominator carb. 10.5 compression running unleaded premium non-ethanol gas.
