it's the luck of the draw..
even when some blocks don't pass the test.. it's not that a 13 to 1 n/a engine will have the pressure build to blow a whole in the wall..
detonation does that..
At finish size I look for minimum of .160 on the skirt sides and wrist pin side I look for a minimum of .100 at finish is size.
I have seen guys with stock builds crack the wall of a cylinder and I doubt it was 13:01
Do a search!!
