Connecting Rod Stampings?

I'm doing a piston swap on a B235R to a set of forged.
I had them layed-out 1-2-3-4. My friend came over to help and I *think* he accidently re-ordered them. Problem is that I didn't write down the stampings on the rods, so I don't know for sure...
There are 2 A's and 2 B's.
Questions:
-Do the the stampings on the rods, A and B, signify weight? Or wrist pin tolerance? Or?
-If the stampings do indicate weight, what would the proper order be? Either they got mixed up or they didn't. As sitting now after possibly being mixed-up, it's ABAB. I *thought* they came out ABBA, but I didn't write it down. Wouldn't AABB make mores sense? Is the rotating assembly balanced from the factory as an assembly and it won't matter with different pistons anyway?
They're getting new bearings and new pistons so that's not a concern.
Any help appreciated!
