The thermostat housing in the head is completely clear.

 

Going to check the timing when my friend returns from holiday. I don't have access to the car at the moment. I think that when he put the dizzy back in he used the old method of turn the dizzy until it peak revs were obtained but don't know if he backed it off a bit. Going to use proper digital timing light this time.

 

That is a recipe for overheating. The optimal timing at idle has little relation to under load and also assumes the distributor is working correctly.

you say pipe goes from the head to the bottom hose! the metro was not drilled on the head for the heater take off (the bolt holes were tapped for the fitting), so have you drilled this or is a sandwich plate fitted below the thermostat housing? either way this pipe should go through the manifold (if a heated one is fitted) or at least the heater before going to the bottom hose. if this pipe goes from head or sandwich plate to bottom hose you are bypassing the rad. 

There may be a little bit out of overflow pipe if the rad is overfilled as it gets to temp and levels out
