Cooling problem

The situation: I just finished installing A/C and heat in my '41 Chevy. It has a SBC 350 Chevy. I filled the radiator with Anti-Freeze. Off I went for a test drive. The temp went to 210 degrees after the test drive. When I stopped, the radiator boiled over.

Additional facts: I had a 7# radiator cap, replaced engine fan with an electric fan and shroud. I did not "burp" the system before running. The thermostat is a 180 degree and the fan is on at 195 degrees and off at 180 degrees.

I'm replacing the radiator cap with a 13# and "burping" the system by running the engine without the cap until it comes up to normal operating temp.

Question: Should I run the heater to purge it or is running it without the cap enough ? Any other suggestions ?
