Is the LSx intake and TB combo that much better over the LS6/ ported TB (for a 402ci) I am getting a 402ci stroker, already have the Speed Inc ported TB and LS6 intake. Is the FAST setup worth it? What kinds of gains would I see?

The 90mm set-up has been show to show good gains, like 15-20. The 78mm do not show gains above the LS6 system. I would wait to see if the LS2 intake is better than the 90mm intake manifold. The 90mm TB is a good upgrade over a ported stock one, from what others with high cubic inch engines like yours.
If you do get it, you can easily sell your LS6 and ported TB, so don't worry that much
