I think the 2" headers might be too big for a stock/near stock LS3 but I'd bet that 1 7/8" headers might work better than the 1 3/4" that many tuners will still recommend (as they do on the LS2).
A heads/cam or supercharged LS3 could maybe make use of the 2" but even then I would think that the 1 7/8" would be fine.
