I understand now. The one engine is missing the thermostat doors at the back which regulate engine temperature.

 Thanks - that is most useful. I appear to be missing the little square 
plates at either side when viewed from the back, so I can look along the 
pushrod tubes from the rear of the car. They are covered up underneath.
I think there is a bracket hiding the rear face of the right head - 
I'll have another look when it stops raining!
Logically, I suppose an engine with a harmonic balancer could be early 
or late, since it is feasible to retro-fit a balancer to an early 
engine, but much less likely that someone would fit a pulley to a later 
engine instead of the balancer.
