Rotating assy balance

That crank has been balanced. Im a little confused. So are the 116 pistons already on the rods? Was the crank balanced with the 116 pistons or was it balanced before? If the 116 pistons are on the rods and those go to that crank put the correct rod caps with the correct rod and run it!! It will be fine that isn't gonna be enough difference to hurt anything. I'm running kbs with factory rods and crank and didn't even rebalance the crank at all .
