It does not matter what crank you are using, as long as the rod length & pistons are matched to it, to obtain the needed approx. 7-to-1 comp. ratio.
The chosen comp. ratio, ultimately dictates the deck clearance(or lack there of) at T.D.C.
Combined with the comp. ratio, the cams lift & duration & timing dictate the running clearance of the valves to the pistons during the rotation cycle.
Large lifts & durations are generally not needed with force induction engines.
So I'll ask the question again, are piston notches really needed on a 930 engine?
