Strange water flow problem 288 cu in engine

Just getting this engine operating
As engine warms water does not flow in upper hose
I removed t stat, thinking a faulty thermostat
After 3-4 min a violent water explosion, 2-3 inches high out fill neck.
The heater hose has water and is extremely hot to touch.
I have no thermostat in
One suggested a purge of trapped air? I don’t know what that means.
