yes it was checked and I checked the bearing cleances several times. I was alittle concerned with the rod bearing clearances so I called hughes since that's where I bought the calico coated rod bearing. they were not concerned with .002" said run thinner oil. I used gibbs 15/50 because the mains were .0033. the rod bearing is wadded up and hard to read.
I have run coated bearings that tight without any problems, and at higher RPM. I was running 10W-30 oil, but 15W should have been fine. Mine have all been big blocks with full groove main bearings to improve rod oiling.
