Hey Brandon it is, I jus recently had my lil bros crank polished and was running stock bearing size and when we got the crank back from the machine shop we did the plasti gauge and it fell into specs perfectly so I think your ok, as long as you were running stock bearing size on the crank before and not over sized or undersized bearings

^Correct.
The real way to do it is to plastigauge it to determine what size bearing to run.
