Default So what should I do next to the LT1???

Well I recently swaped the cam in my LT1 T/A and now I need more. What would you guys do if you were me? I have a custom cam (same as the cc503 with a different lsa), 1.6 rr's, springs, long tubes, 30lb injectors, and tune. I already have the gears, cai, exhaust, and free mods. What do I do next for more power???
I am thinking about pulling the heads and having them worked locally. Is this the only option I have left? Plus, if I do would you guys swap the cam again? BTW I'm not a fan of NOS and Please don't tell me I should have went LE2 set-up. I went 503 because I figured this would be the best route for me but now I have caught the bug!

What would you do????

+2 Elliott's AI dyno numbers through a stalled a4 speak for themself. I wouldn't worry too much about the ported intake, but a nice set of 200cc AI heads will wake that thing up and make it a beast

Thanks guys but one more question???
I take it everyone would go with the AI heads or LE heads instead of having mine worked locally?
I have heard nothing but good things from this local guy and the price difference makes me think it would be a better decision. Buuuuut i'm still very open minded to comments that you guys have. Anyone have a ball park price on ai or le heads?
Also if I went ai or le would you guys swap the cam again?????

Don't do heads without the intake, IMO.

LE and AI aren't the only guys in the world who know how to port a set of cylinders, but since they are both nationally renowned companies it's easy to recommend them versus people in your local area that we have no knowledge of. I had my heads locally ported and am very happy with the results, but just because there are guys local to me that can do go work doesn't mean this applies for everyone. if you want to use someone local I'd recommend talking to some local shops and racers, people whom either own or built proven combos and find out who does their machine work. usually when you talk to a wide range of people and hear the same name pop up enough times, you'll have a decent consensus of who can get you the work done you want. never trust a single man's word, always get multiple opinions because everyone has their preferences.

but if you do decide to go with LE or AI I'm sure you'll be happy with either

That's kinda what I am concerned about. I am not sure if he has done any lt1 heads. I have heard from many people that this guy does great work. The only negitive I have heard is he's slow. I could careless about him being slow because I plan on having it done in the winter months.

I'm still up in the air on this. I need to check the prices on ai and le.


Thanks for all help fella's..
