Exactly.
The cylinder head cannot fill with coolant because the thermostat is closed. The coolant fills the radiator and the lower hose and comes to a dead stop at the thermostat.
The only way to get coolant into the head is via the upper hose. You've got to remove the upper hose and fill the head with coolant which will eliminate the problem.
