weird temp gauge

I've got a 90 f250 with the 5.8L, and shortly after start up the temp gauge goes over to hot and the heater blows cold air. After 5 to 10 minutes later it goes back to normal and the heater blows hot air. My guess is the thermostat.

Yep, it's your thermostat. Get a new one from ford not your local auto parts store and that will cure the problem.
