Dan, I run a seal power moly top ring in my 350/455 Buick stocker motors. On a freshen-up[rehone,new rings and bearing], I use 30w oil Valvoline,castrol ,etc.with 16oz of Lucas break-in lube. I run the motor in the driveway for 5 or 10 minutes or one heat cycle, I set the timing and check for leaks,then check valve lash,etc. Off to the Dragstrip, I make 5 passes on break-in mix, Then change oil and filter to 0w20 Mobil 1 or Castrol 5w20 synthetic.
