Out on the water overheated. This is what I did. Replaced water pump, thermostats, diaphragms, therm seals, and hoses both sides, new head gasket starboard side. Started motor, port side 158F starboard side 183F. I shut down motor when temp reached 183F on starboard. Whats going on completely confused and a bit aggravated. Please help?

hows compression?
sometimes a leaking head gasket will pressurise the cooling jacket
did you shave the head flat?
