Doing it right the first time

I've been battling an oil leak for a long time. Stubborn and cheap as I am put new pistons and rings in with just a monkey ball hone. After multiple oil pan gasket and rear main seal replacements. The conclusion is the rings aren't sealing and its blowing oil out the rear main.

I have another 360 block that I'm going to bring to the machinist to have bored,decked,etc.
.030 h116 speed pro pistons, scat I beams, .010 stock crank, ede rpm heads, ede air gap, 60403 voodoo cam, 750 holley street hp.

Going to need different rings (what would you recommend)
anything I should test before taking the engine apart/while taking the engine apart?
didn't have problems (leak oil) with the old 405cp pistons/stock rods. If I find another crank I could throw the bottom end back together with the old rods/pistons.

thanks
