I always replaced bearings all at one time. That is engine taken off and over turned and working on it upside down. Working on it right side up, you might want to do one at a time. I always (with engine upside down) would replace all intended bearings and then torque the entire main and rod caps to speck useing plastiguage and then take all bearing caps lose again. I would then see if the plastiguage would correspond with engine specks on clearance. If all checked out OK I would put bearing caps on and torque back to speck. Doing this with engine upside down is easier and probably more accurate becuase the weight of the cranke will not smash plastiguage before you do the initial torque. No gravity concern when doing it upside down. The crank is alot heavier than your bearing caps in other words. I always plastiguage with dry bearings and if it checks out OK I prelube the bearings when I reinstall the caps after checking clearance. You will have to check the specks to see of .005 is acceptable. You might do a plastiguage check on the entire width of new bearing. Maybe it is .005 at a certain point, but .001 out on the edge or something. If you put plastiguage all across the bearing, maybe a variance will be found.
