Generation III External Engine - looking for more power

Hi everyone im new to the site but iv seen a lot of knowledge in here. Im looking to get more power of my car & i want to stay n/a. I have an a4 ls1 with lots of bolt on. Here is what i have:
Stock bottom end with an comp cam 224/224; 5.88-5.88 lift 114 lsa
Ls6 intake with an power throttle 85mm throttle body
Texas speed ls6 heads stage 1 with 918 springs, ls7 lifters
Under drive pulley
Mti box & smooth below
Performents built trans stage 2 with 2800 stall
E locker limited slip with 373 gears
Konis sport adjusteble
Subframe conectors, eibach sway bars, h&r lower springs
1 7/8 hooker headers, hooker y pipe & borla 3 inch cat back. Im not running cats.
I dyno it befor new trany & new exhaust & borla & did 383rwhp, i want to make more power & thinking low expenses maybe putting a bigger cam & port the heads more would it make a big difference i would like to get at 450rwhp well thats what i like to have but i dont know if that could be posible with just this!!! Any advice i priciated, thanks in advance.

I forgot to mention i drive the car everyday so smth streetable lol

Anyone!!!

Put a bigger converter in it and get a GOOD set of heads

This.....

Thanks. Just tryin to stay low budget thou, a good set of heads would be at least 2000$!!!
Dnt have that money now...

Nitrous......
Or
Different heads, cam, and intake

Thanks again guys. So doing some port work in the heads i have & a bigger cam wouldnt make a big difference? Is that to fare from what im aiming for?

I thought someone would say something if thats worth it or not!!!

you have a pretty good combo.your heads are OK ,not much more you can do to them.maybe get some better springs like some PAC 1518 .if you get a higher stall you could get a bigger cam.a big EPS cam or Trex cam mite get you close to 450hp.get some comp cam trunnion bearings if your rockers are stock.look in the dyno section for cams that you mite like.

Thanks garygnu i wanted to go with a higher stall but since i drive a lot in freeways i decided going with 2800 ill check out them trex cams i heard they r preaty good too. I was thinking tourqer v3 but i dnt know how they r on a4!

What do you guys think on the EPS 234-246 6.02-6.07 on 111 lsa for my set up. Would it be a good cam on a A4 & actualy giving some power?!
