Answer:
There could be three answers to your problem that I have the ability to see:
1. As has been stated before you have crack in your engine block or head (it's not impossible but not so common)
2. The gasket between the engine block and the cylinder head is damaged.
Both 1 and 2 means that pressure from cylinders enter the water circuit
3. The heat is very high (over 100 degrees; subjective depending on environmental pressure) and water becomes air which rises the pressure in water circuit.
Try looking first at water temperature. If that's the problem then you should consider a fault in water cooling system.

Answer:
When the cylinder head was removed do you know if it was pressure tested for cracks & machined. or did they just replace the head gasket.
Sounds like the system is pressurising which could be caused by a cracked or distorted cylinder head.
If the temperature is going to high it might be the cooling fan isn’t slicing in causing local boiling and forcing the water out.
Hope this helps.

Answer:
You could try dropping the radiator and sticking a hose into the top hose mount to flush out any debris which might be causing a part blockage. Run the hose until the water runs clean from the bottom hose fitting. Remember to open the heater controls first to ensure that the heater matrix is cleaned also. Afterwards, flush the radiator.
