replace ls2 rod I just ordered a ls2 setup of rods and pistons, atleast one needs replaced. However these look offset, so do i need a rod of the same side (number 2 even side) or can I just use any ls2 rod?

All 8 stock connecting rods are the same, even go in the same exact orientation. Basically the connecting rod bearing tang is installed facing the drivers side of the engine on both banks.
Now the piston pin bore in the pistons themselves are machined offset. Again, all 8 factory pistons are the same due to lack of valve reliefs, but as long as the piston dot (for front) is aligned to the front of the engine, there will be no issues.
So in a stock LS1, LS2, etc: All 8 new OEM pistons and rod assemblies can be swapped around in any cylinder, they will all interchange. Bearing tangs to the drivers side, piston marks to the front, easy references.

Yea sorry I didn't make that clear, my issue is with my rods. I'll simplify my question.
If I have to replace a rod, does it need to a rod from the same side.like a gen 1 sbc where the oil holes for the cam are directional. Or can I just buy a rod and go. If this isn't.ear I'll have to get pics lol

No, GM made only one part number for the rods in any engine. There is not a driver's side rod and passenger side rod. Same goes for the aftermarket rods.
