I ran a set of +.040 TRW forged 10.5:1 pistons, honed with torque plates, and mains torqued to spec, to a plateau finish for Speed Pro file to fit Moly rings. The heads were milled .040 and .038 on the intake side to get down to NHRA min spec. Chambers were equalized at 64.8 cc. And the chambers were centered over the bores with offset dowels. Bowl cleanup, and intake port gasket matched on top and sides. Same for the exhaust ports. Always thought you had to know what you were doing to port heads. That was not me.
