I was always taught by my old man if I ever have a hot radiator to refill if very slowly dribble a little bit of water at a time and while the motor is idling over so that any change in temperature does not crack the head. I did it with any the old Holdens I had and never cracked a head. This runs and drives the same as it did wouldn't a cracked head stop the motor or change it noticeably!?
Seems to me like the water must not be flowing around the motor properly because this is what cools motors so I'm hoping it is the thermo when i find it as that seem a logical solution it that's blocked then water could not flow. If water wasn't flowing because of the thermo then filing radiator would not go the head as much too.
The old Holdens had cast iron heads, these transits are aluminium...sudden temp changes can do horrible things to them. He says you may have a cracked head because your cooling system is possibly pressurizing itself more than would be normal.
Thermostat lives here... #2:
