It's probably not worth it. With that money, you could have bought a set of ported heads.
LS6 intake (which you've got now), ported stock throttle body, cam and heads would give you one helluva fast car. 450rwhp EASILY.

I guess this is just prep work for my cam...

I have a 90/90 on stock internals and I noticed a little improvement. I havent had it tuned yet because my dyno guy seems to be avoiding me so I dont have any numbers.
I'll say 10 ~15 hp at the most with your mods (after a tune).
I picked up 10 from a 78 FAST with my mods. Before the tune I was actually down a few HP. So yes a tune or at least touch up is needed to get the power out of it.

....I'm with you! 
By itself the fast 90 is going to hurt you down low. Now, I would wait to put it on when you do the cam and heads. Then it will be more of an improvement especially when your turning up to 7000rpms.
guys u act like im not planing on getting a cam and some afr's at the end of the summer... i just wonted to go ahead and do it sence it was the last bolt on there is for my car (besides the ewp that im not interested in)
Your original question wanted to know "will i gain hardly any with this intake w/ stock internals and such" and everyone told you what they thought of the idea. It's not what you wanted to hear and you already bought it so put it on. You know you are going to with or without our opinions anyway.
Sounds like you are planning all the right moves, the questions here appear to be more in the order of execution. Not sure how much you will pick up. The question is if you get it tuned and then do heads/cam later, will they touch-up the tune or charge you all over again? With the tuner I go to, he charged an up front initial tune and then as I made more modifications he charges a lower fee to touch it up.

If that's the case, just slap it on and lets see how you do. It would be worth it just to find that out.
