I suspect that your problem was a combination of no thermostat, a non-working temperature gauge, and quite possibly a problem with the head tensioning such as incorrect sequence of tightening or a binding thread resulting in uneven tension.

Just a quiet query here to those more mechanically ept than I - in the 'old' days after an engine rebuild, we used to whip the rocker cover off (if applicable) around the 500 mile mark and check and redo the head bolts, re-torquing them down to make up for any play now that the gasket had been compressed for a while.
Do people still do this or is it no longer deemed necessary?
Just wondering as at 1000km when it failed, it may have just needed a re-tighten before the trip.

I drove it around a for about 200km then re-tensioned the head bolts and got a mechanic to give it a health check then headed off.
ah - shoot - sorry - missed that.
it was only realy a requirement on old cast iron style engines with old school gaskets...
the forerunner of the newschool gaskets were called monotorque for a reason.
at about the same time as the new style composite gaskets became common place so did torque to yield headbolts.
