Kees,
I fully agree with your comments but suggest it is probable (although not a
certainty - it could be poor engine timing) that in this case it is the
friction in a newly rebuilt engine. When that goes so the temperature
should drop to similar levels to the other engine.
Relating this to your explanation - I am suggesting the overload is the
additional friction from the newly rebuilt engine, when that goes so will
the higher than wanted temperature.
Time (and engine use) will tell.

Guy,
"A thermostat cannot control heat beyond it's maximum opening
temperature" is absolutely true. Problem is idealy the coolant should
never get that hot, certainly not when running in, as it is a sign of
overload..
I have always used thermostats with a high as possible opening
temperature in any car. This increases the operating temperature and
efficiency of the engine. It also increases the temperature reading, but
in my experience this reading will remain constant at all times (new
engine, old engine, rebuild engine), unless overloaded (mountains, very
fast German autobahn driving) when the temperature will creep up and
slowing down is needed.
(all assuming that the engine and cooling system are in good nick).
