From my experience, the piston ring side clearance is critical. With new rings there will be more "bite" or friction on the cylinder walls. Therefore the ring side gap will typically get pounded and enlarge during break-in. So the rule of thumb is more than 0.004" side clearance with new rings and the piston is done, not worth re-ringing.

0.006" sounds a little tight for end gap, but I will defer to the experts.
