Crank journals tend to vary, some more than others. The guy I work with fits bearings all the time. Sometimes he'll polish the crank to get it to the right spot, sometimes he mix and matches bearings halves to get the correct clearance. That is just how it is these days. You can send the crank back but there is no guarantee that the next one will be any better and you'll be out $200 for shipping plus a couple of weeks of shop time.
