What rods do I use? Anyone know what rods are used with LS6 crank part # 12583565, full floaters or pressed pin? I'm getting conflicting data from GM LS6 specs.

Depends how accurate of a balance you want. The weight difference will be in the small end bushing and the c-clips. It's probably only a couple grams, which if you're just going to rely on the factory balance job, probably isn't much anyways considering the manufacturing variances are probably even worse. I think floating/pressed pin rods depend on the year, but I'm not 100% sure about that.
I was under the impression the crank would be balanced before assembly anyways.

First, thanks for the reply. I wasn't sure if the floaters were all that much heavier. I should just weigh them!
You're right, I should just have it balanced, however it was factory balanced and I have both sets of rods and pistons.

Ok. So I weighed the 2 sets of rods/pistons. The full floater set up weighs 70 grams more than the press fit set up. That sounds like a lot to me. I'm still wondering what rods/pistons I should use with this crank. Anyone?
