Performance advice
A good breathing exhaust, good cold air, mid's 230 camshaft and good tuner should get you where you want to be power wise.
The parts list will depend on your budget.
Does it need to drive like stock?
Do you care about fuel mileage?
Stock LS2 intake manifolds are crap, so a FAST intake should be in the budget. Halltech cold air intakes are great. Headers I would do 1 3/4" if you don't plan on adding forced induction. Kooks and ARH are my favorite unless you can find a used set of Pfadt's. I have Pfadt headers and they made 437/427 on my LS3 with a stock cam, ported LS3 intake, and Callaway Honker CAI. It wasn't enough and I added a blower, lol.
As far as heads go, you should be able to get 450rwhp, but more than that and you either need ported heads or aftermarket castings. The Trickflow 235's are great cathedral port heads. Advanced Induction does a really good ported 243. That would run you about $1k with them. But you would be waiting while your heads are being done.
By the time you spend all that money it would have been easier and about the same money to just add an ECS blower. You can get them for $5200. It will drive like stock until you get on it and still get great mpg(unless you change the cam also).
The mods are complimentary and need to be done in order, with the overall goal in mind.
Hopefully this will help explain what you will get for your money. The first few make the biggest difference, headers and tune.

I think your budget is reasonable if you do your own work, not so much if you add installation costs.
Supercharging is great bang for buck advice...
Care to share your age and previous performance car experience?
Best wishes on your build!

On my full bolt on 06 A6 I went with a spinmonster cam (230/234 612, 598 114+2) and Advanced induction 232cc 243 heads. The spinmonster cam is a well proven daily driver cam that makes good power and has excellent street manners. It also was highly recommended by Pat G(LS1 tech cam guru) for my build. The AI heads fully ported and assembled with ti retainers, dual springs etc are approx. $1600. Trick flows are about a grand more. There are many threads on corvette forum if you search "spinmonster cam". There are also some great threads on cam only, heads/cam builds and a long thread on N/A vs supercharging. There's a lot of great reading. I would research as much as possible so it's "buy once, cry once".
Your going to want a better oil pump, new timing chain and an ls7 lifter kit. You don't have to but I did a trunion upgrade on the stock rocker arms. After all the parts, you can figure another 2k or more for install and tuning. The installation costs is the most painful part for me since I can't do my own installs anymore(paraplegic).
