Jeez Louise , I have 0.038 piston to head clearance , that be good enough ? And I have a similar build and did not hit the magic 430 hp , torque yes , still looking for HP
You might have .038 at the areas the deck surface has material, not any quench with the parts that were used. The open chamber has ~.060 step and there is no way to do anything with it unless you use a quench dome piston. .012 out of the hole, .050 gasket and open chambers is really irrelavant to a quench discussion with that extra .060 step.
I'm guessing he may be looking at something like the Comp XS282s camshaft. My friend had one 10:1 340, eddies, 282s, victor and a 750 or 950dp. Made 455hp and about the same TQ.
