CM 2250 liner protrusion

[Running rough]

0.014seems to be what cummins is recommending, I know my 870 is sitting at .009 to .010 on all the cylinders and it seems that's how it was set at on older blocks and they got away with it for the most part before liner seat fretting was so commen of a problem, but defiantly I would want to see 0.014 on any new or rebuilt engine just for peace of mind
