Your apparent binding problem is quite likely to be caused by the centre main being misaligned WRT the front an rear mains, this isn't an uncommon problem on 3 bearing A7 motors. Have you got the block bolted down to the crankcase when you have this issue? that is likely to make a difference.
If you just want to check the shells and crank journal for clearance, put the shells in the centre main housing halves and bolt the two halves up either with the crank out of the motor, or without the front or rear main bearing in place.
