What's a good manifold swap? One where you don't break your oil pressure sensor!!
Honestly, unless you're running forced induction, high compression, or some other kind of major internal mod, then the LS6 will give you about all you want. There is a recent (I think it's recent) GM High Tech Performance article that I can't find which compares the Fast 78mm, Fast 90mm, SLP LS6, Holley aluminum, and LS2 intake. This is not the flow test that's on the sticky at the top of this section. It was a dyno test.
Basically, it showed that the Fast LSX 90mm was the best. The Fast LSX 78mm one followed. Almost identical in numbers was the LS6. The LS2 was actually worse than the LS6! Then, the Holley finished up the field. Basically, all of them were within 5 hp of each other, except the 90mm Fast intake. But, you also have to have the 90mm throttle body and larger MAF to go with it to make full use of it (what's the point of having a 90mm intake and throttle if your MAF is small?).

The total crossectional area of the intakes are listed below:
Stock LS6 w/ 75mm openning - 441.5625 cm^2
Fast LSX 78mm - 477.594 cm^2
Fast LSX 90mm - 635.85 cm^2
The 78mm one is only 8% larger, while the 90mm is a whopping 44% larger! And, to give you an idea of what that means, remember that the 44% larger one only turned a few extra ponies (maybe 10 or so) than the stock LS1.
