Is it worth porting the fast 90 intake? tb? whats the hp difference after porting?

I just bought one and I wanted to see what the difference was that way I could get it done before putting it on....I have the ls6 intake and a 85mm tb...is the fast 90 tb way better than the one I have? what do you guys suggest? I want my car to breathe as good as possible....

I've heard it is worth 5-10hp in the upper rpm's. With the more you have the better your gains will be ie; more cubes, bigger cam, better heads.
