Intake Question
A ported TB won't be to far behind the BBK and will save you a couple bucks. Remember the LS6 can only flow so much and the stock TB ported is about good in my opinion.
The 85mm BBK doesn't have a good application. On an LS6 intake you're better off with a ported stock throtte body. The 85mm intakes don't keep up with the LS6 intake. And the BBK won't physically bolt on a fast 90mm intake, so it's not a good mod.

the fast outflows the ls6 on any application, its like when people say the stock maf is good for 500 hp, that may be but its still a restriction, go for the fast intake, i remember i put mine on when i just had a cai and still the stock manifolds, i felt the diff, go for it and dont look back,
