Most head gaskets are considered no re-torque. Meaning once torqued to spec that's it. However, I do know some guys that torque it and while on the engine stand will wait a day and re-torque. Not really necessary if you use a good no re-torque head gasket.

Does the head gasket need to be changed when putting in a starter?

Typically not no.... the starters is normally located on the underside of the engine where it connects to the Fly wheel, which in turn is connected to the Crank (this is a simple explanation) The head Gasket is located, typically, on the top of the engine, where the 'head' of the engine is. The 'head' houses the cam and lifters and Valves. In short, no, no need to change the head gasket if you are changing the starter. (NOTE: My answer assumes that by 'starter' you mean 'starter motor' on a standard type engine in a car.)
