Smallblock Pistons: 1 question.....KB's -or- Sealed Power(SpeedPro hypers)???

One thing I'll correct is the part about balance and stock weight pistons. You dont want factory balance, nope... especially if you have the chance to correct it.
So the OP will understand: Do you mean you want it balanced to a much tigher tolerance than factory (even if it is stock weight parts)? Or are you recommending he go to lighter pistons/rods and rebalance for that to get to lighter rotating weights?
