Mark - Good advice from Howard about the radiator cap. A 7# cap would be my choice. Something else to consider: A 180F thermostat may be too high for your altitude. Water boils at lower temperatures at higher altitudes. The 180 thermostat may not be giving you enough gap between when it opens, engine reaches operating temperature, and water boiling point. Try a 160F thermostat and a 50-50 mixture of permanent type anti-freeze (green colored) along with a good radiator cap.
