Well the question explains its self, and no I'm not getting new heads. I just wanted to get better air flow and gain some HP. If does fit what adjustments would I have to make!?

If you aren't getting a 4" bore with rectangular heads on top of it, you aren't running that intake.

Ls6 or FAST are your two main options.

A rectangular port intake is not going to work on cathedral heads

Like everyone else mentioned this intake will not work on your stock LS1 heads.

Thanks Guys, Now after doing a little diggin I've narrowed it down. Ws6store sells both F.A.S.T. 92mm & 102mm all together with a fuel rails and throttle body its $1699. However they also sell the BBK intake w/ 85mm throttle body & fule rails for $980

Which one is better?
Is the F.A.S.T. set up worth the price?
Where can I find both these brands used? didn't have any luck on ebaymotors or google.

If I remember correctly the BBK's horsepower/torque increase was only a tad better than going over to the ls6 manifold (given you dont have one).

You have so many mods you should address before dropping that kind of coin on an intake.

Ls6/ported TB will take you a long way. (roughly 375$ and milar gains as the BBK setup)

You can find any of those intakes on a regular basis in the classifieds.
