My understanding is the rule of thumb is that you "should" resize the connecting rod when you replace the bolts. The big end gets distorted in terms of roundness in relation to the clamping down of the specific bolt. When you introduce a new bolt, the relation of the clamping down force has changed.

But resizing requires having the rods and pistons removed and taken the a machine shop. At that point it is "Might as Well" rebuild the whole motor as you have to remove the head to get the pistons out.

My opinion is you would get by fine without resizing on a stock motor and a used crank.
