Thanks Jerry for the suggestions. The heads are iron vortec truck heads and the gusher was definitely coming out the hole in the heater hose. I lost a little pressure when pressurizing the system, but it could have been my old Stant tester leaking. No steam or antifreeze smells on startup. I drove it hard for a hundred miles on the interstate with no issues so I am assuming we go forward hopefully with no problems, while watching the oil and coolant for signs of leakage.
