ACL bearings are where it's at. Polish and mic the crank while it's apart to make sure it doesn't need a grind and be sure to check the clearances before you put it together.

something a machine should do. You chuck the crank in a lathe and use different abrasive belts to polish the journals and get rid of any slight imperfections.

It should run you about $80 for them to clean and mag the crank to make sure it isn't cracked, check it for straight, mic the journals and them polish it.
