Generation IV Internal Engine - Intake question

Please help, what's the difference between the LS1 LS2 and the LS6 intakes. Which is better on stock bottom end 00' C5 Vette., full bolt-ons and a lot of gas????

ls6 is what I have the most experience with, although lt1dave on this board has had great success porting the ls2 and is pretty damn close in numbers (less than 5 rwhp) to a ported FAST 90 mm intake. I would give them a call for more info.
