In the mean while the rear heater is blowing really hot. But the front heater gets cold then hot cold then hot and so on. The new radiator that I put in is twice as thick as the original does that have anything to do with it. I just cant seem to get this thing to run a stable temp.

You should not have that much temp swing with the new thermostat...maybe 190-205 once its open and regulating.
You may still have an air pocket
