Another point. I have read where some builders will hand polish rod journals and end up with slightly different journal diameters. They then measure each journal and each bearing and put the tightest bearings to the smallest journal. I have heard of people mixing bearings, where one journal my be standard and another 0.003 under.

It is best to measure each and every bearing and journal, as you never know what may have been done in the past.
