When you say rebuild, are you getting the crank turned and rods resized if needed? If so, then it "shouldn't" matter.
I was not going to get the crank turned or the rods resized. Problem is when I removed the pistons I marked them with a punch as I didn't see the original marks. Once I got them out I realized that I had marked over the original marks so now I'm not sure where they go...

If you were keeping the original pistons, rod bolts, etc., then the factory balance job would suffice.
However, since you're changing the pistons, I'd get it balanced for sure. And while you have to have a shop press out the piston pins to change out the pistons, might as well replace the rod bolts and have the rods re-sized; all of this cheap insurance to not having a blown motor down the road.

This ^^^^
Nevermind that the KB's are lighter than a stock piston, also not resizing the rods considering what you state above is just asking for trouble .
