Is .002" piston clearance enough on these engines?
NO! #3&#4 with the larger bores at 4inches need .004 clearance. The two back clylinders run hotter than the front two. I would make all four .004 clearance, Someone had problems with his engine seizing, after several tear downs he increased the bore clearances to .004 and his problem was solved.
