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.
Don't force it with a little hammer tap, tap, tap
get a bigger hammer tap done
