Do a quick search on LS1tech and I think you'll see the LS9 gaskets are the ones to use for boast. Basically, a LS9 is a supercharged LS3. The LS9 gaskets have more layers and supposedly seal better under boost conditions. I'd bet Thompson meant LS9 gaskets when he told you.

If you only have 2k miles, then you don't need anything else other than mybe new valve seals, switch the springs over, new gaskets, and anti-freeze. I always like to change oil/filter after a head swap too.
