I wouldn't worry too much about mileage on the car, I've got 18k miles on mine and do what I want to it. But I also keep all the stock parts just in case. It's just a car, enjoy it while you've got it.
Edit: you'll also need a good clutch for much over 400rwhp, that's another $1000 or so installed.

I agree that $12K is a lot to only achieve 420 HP.
-Kooks headers are very good but very expensive.
-I don't see the value in porting the stock LS1 heads-let alone "polishing" them, which really isn't done anymore. The word "polishing" is just a sales trigger word these days. There are heads on the market that are waaay better right out of the box-with all the features you mentioned LPE would do.
-Porting and polishing the original LS1 throttle body won't bring you any gains.
-Using the original intake manifold-it's a LS6 manifold in this case, won't bring you any gains.
The point is you can make better HP numbers while spending a bunch less money.
