It has the original 216 motor in it and it ran until I quit using it. I currently have the oil pan off and the head off for some minor repair. The engine is free and everything turns fine. However, for not being used for a while, the cam shaft has some tiny spots of rust on the suface where the lifters ride. Does this mean the cam is toast? Should I replace before trying to start it. or will these spots wear off with the motor running?

Minor surface rust will polish itself away with a few minutes' running time. Look at a disc brake rotor after just a few days of non-use. The cam lobes are constantly bathed in splash oil from the crankshaft and rods, so slight surface rust will disappear even faster than a brake self-polishes.

Likely it's just minor.
And will go away very quickly.
You might think about changing the oil after a couple hundred miles just to get any junk out of it.
