Swapping rod bolts with out resizing the rods is a sure way to end up with spun bearings.
You can check them for roundness after you put them in, but what you will find is the caps don't align with the rod. It usually moves the caps around a few .0001's (Thats tenths of a thousand or more) because the new bolts don't hold the same center as the old bolts. In the 40 years I've done engines I've seen spun bearings many times when someone does a freshen up themselves and doesn't size the rods after changing the bolts. In some of their instructions ARP does suggest the rods be sized when changing bolts . Have your machinest cut the cap and rod side about 1 1/2 to 2 thousandths each and then put the bolts in and resize. That will give enough to work with and it will only shorten the rod 1 to 2 thousandths. It is my opinion that you might roll the dice and get by without resizing, but that is one of those pay now or pay later things.....

Look at step 4 of the ARP instructions from page 33 of their web site about How To Install OEM-Style Bolts.
