Getting my 360 Sunday, whats the first thing I should do to it?

The engine runs as is, so I could just install it and run it. But of course I kind of want to take the heads in and have them look at it, or maybe install a cam.
Is there anyhting you suggest be done? Or since it runs as is, I shouldn't ruin a good thing and use it as is and keep my money.
I'll have about $700.00 to play with.
