Upon  closer inspection, I determined that these bearings were rubbing
against  each other in transit and it even appears that the sharp corners of
some  had scratched and put dents into the surfaces of others.

My question  is: How important is it that face, or crank side of the bearings
be  perfectly smooth?


Jedd,
In my opinion, the surfaces that contact the crank should not have any  
raised portions due to gouges. Small indentations won't hurt. if there are any  
raised portions einther file them down or gently tap them back in with a small  
hammer (ball peen is best). Just remember that you want a constant clearance of 
 about 0.002 in. between the journal and the bearing. 
Scratches probably are all Okay because they likely contain no raised  
material.
