You should be able to move the caps & rods on the bearings there will be some float check each if on is not moving back it off and see if the engine will turn by hand, did you check the oil clearance when fitting the bearings why did they need replacing? Did you damage a journal with a faulty bearing?

You will need to at least check journal dia and condition, if not to specs a grind will be required.
