Ideally end clearance on the oil pump gears should be .002-.003. Gear lash should be max of .003-.004. There should be zero pitting or visible wear on the gears. If you have visible scoring or wear on the pump cover or gears it needs to be corrected.
At .004 your rod bearing clearances are getting pretty sloppy and will undoubtedly have an adverse effect on oil pressure. Did you check camshaft journal clearances or just hope fior the best?
Remember - the wear limit is the absolute maximum acceptable clearance and well beyond what you want new. A rebuild that starts out at or near the wear limit isn't going to perform "like new" or last very long.
