None of them.

Get a set of headers and a real tune.

Youre gonna need a reason to move more air with a bigger intake before you get one. Get a cam, long tubes, and a real custom tune first.

I may be biased, but I vote an LSA kit from one of your favorite vendors on here

With the rectangular port heads and truck intake you arnt going to find an intake that will actually flow better, and as far as i know the fast intake is a car intake.... Look into a cam and with as big and heavy as your truck is probably keep the vvt so you can keep the low end torque, youll need it!!! Aside from cam, i agree longtubes, good tune and possibly a higher stall converter.....
