The HP gain is due to a little difference in plenum design and the 90mm T\B setup. They are a 3 piece design and use the same 4-bolt flange layout as a FAST\TPIS 90mm so they will bolt right up. So I feel that they will be a good mod for the money spent. 
Power from LSx

You need to be reading more. Please check Popular Hotrodding and Hot Rod Magazine last two months. the LSX intake does almost nothing on a stock motor. Throttle body or not, Increase the air intake and exhaust capabilites with a cam and headers, and the LSX intake begins to shine. Based on that information, I would imagine, that the LS2 intake would do the same, by that I mean nothing on a stock motor, but add a cam and headers and it would shine also. The real question is approx 30hp worth $1300.00

Unless you have an LS1 intake or you have a 224 + duration cam, swapping to the LS2 would not be worth it.
The LS6 is plenty untill 450+rwhp.
90mm TB and intake will need all induction mods also otherwise it would be like sucking through a straw.
There is always the new BBK SSi that has porting/matching capabilities and is said to make 15% more flow than LS6. And before you say it, heat soak is not an issue on the street (Loss is super minimal)

That is what I am waiting for too. That with LS6 MAF and custom air intake should work well

I don't trust magazine articles. Oh, they mentioned somewhere in the article that "before" was in 90 degree weather, and "after" was in 40 degree weather, with no correction. Just "gained 4 tenths". Yes, this was in a "respected" magazine. 
I talk to engine builders and dyno owners, as well as paying attention to who has problems with it (there have been), and what other cars are dynoing.
As for stock motor... Not here.
As for bolt ons... Name one. I have that. Name another. I have that too.
