An old school trick for an engine that was going to sit for a while was to pour a quart or two of good old fashioned trans fluid down the throttle to coat the intake valves/pistons/rings and turning the the engine over manually a few times. In your case, I'd remove the valve covers and pour a bit over all the valve train parts as well. It'll stop the rust and prevent any new stuff from forming.
As has been stated earlier, any fine surface rust will dissappear quickly once the engine runs for a bit - much like the rust on a brake rotor. You'll probably want to change your oil after a few hundred miles though, as there will be very tiny rust particles circulating through your engine.

I hate that. Why is it some metal smells like puke when it oxidizes? I've been tossing in the little silica packets that come with stuff in my tool cabinet(s) drawers and that seems to help a little...
