pg 20 - fixed cyl height w longer stroke crank means shorter con rods which increases lateral loads on cyl walls. cyl wall scoring showed up on the 997 engines w the move to longer stroke. piston size not as much of a factor (note the variety of bores on the m96 engines, but bore scoring not typically a factor on these engines). of course, improved cyl liners seems to have fixed it all:

Its all in the combo. This combo has taken since 2007 to develop, and I've shared all about it that I am willing to.

Stroke, rod length, bore, valve sizes, port flow margins, CR, and every other dimension within the engine is altered in some way with this combo. None of these are OEM Porsche dimensions, to include the stroke.
