I'd say skip LS6 and go for F.A.S.T. they come in two sizes 78mm or 90 mm to fit the size of TB.
I'm very happy with the F.A.S.T instake I have, I wanted to change my LS1 intake for something a little better, was thinking of the options for some time, did consider LS6, but then thought if I'm going to change I only want to do it once. So took note of what people had to say about it and made my choice.

I think heat soak is a real issue.
Just look, for an analogy, at a hairdryer or car heater, air passed by hot filiments and boom, instant hot air. Same principle applies to a manifold, air passes through a hot manifold, boom, heated air.
Now whether or not it makes much of a difference is unknown, and untested as this point from what I can tell.
But to answer the original question I would run an ls6 intake hands down, unless I was boosted or had a heavy head.cam combination. Even then it works good, just not the best.

I never said 400rwhp was capable w/ bolt-ons. I was basically wondering what the most powerful factory freaks were.
Oh and any car will start getting slower as the engine gets hotter and hotter.
However how many times is the engine maxed out during a race? Usually just once. Your not running a lemans or anything.
Oh and race engines use metal intakes.
