Is it possible that you fitted a type of thermostat without a venting
'jiggle pin'?
I had this problem many years ago. What happens is that with the
thermostat fully closed and no way for a small amount of coolant to move
around the system and allow warm coolant to reach the thermostat bellows
the thermostat doesn't open.
The coolant then boils inside the head. This cases back pressure and
forces coolant out of the radiator overflow. Eventually steam or hot
coolant will get to the bellows and they will open.. The system then
operates normally as you describe.
I suggest that you have a look to see that you have the correct type of
thermostat fitted.
