So I re assembled my build in a new hemi block. My old block had deep pockets almost holes on the head to block mating surface from when I went through 2 head gaskets. So I scrapped the old block and opted with a new fresh one. Also got a new piston,stock length ARC rod and a .47 head gasket with fire ring. Cross cross torqued my head bolts to 20ft lbs. in steps. Cleaned my head up and re assembled it with a fresh valve stem seal. I put everything back together and checked,torqued,and made sure everything was clearanced. Second start up after 1 heat cycle with hi zinc oil. Fresh oil and race gas 110. Runs great. Road test next
