" It is going to have max wedge heads"
Those In and Ex ports are huge! Those heads will be perfect on a 500 plus cube engine. Cant go wrong with a quality stroker kit. The piston and rod assemblies with a quality kit weigh SIGNIFICANTLY less than stock rod and piston assemblies. My brother had stock rods with old reliable TRW forged pistons on them in his old school 440. The Arias piston and (don't remember the brand of rods) after market rod was astonishingly lighter than the old reliable tuff. Youll have a big cube fast revving reliable monster!!!!!

Maybe I didn't catch it but are you going with a roller cam? Expensive but worth it.
