Makes sense.
Depending on where the top of the top ring is, plus .040 for keeping the ring sealed under any situation, it might get a little tough to notch the block much. I assume though that the rings have to be moved down a lot lower than a stock type piston, so valve notches can be used for bigger cams? Anyone have an idea how far down the rings have to go? I hope to bore mine to 4.000 or close.
