Yup.  I'd thought of that.  Perhaps pull the thermoswitch connector and
drive the car around until the temperature just goes above 'Normal'.
If you stop it at that point, the residual heat buildup should take
the head up to 130c at minimum.

The great risk isn't stripping the threads - it's snapping the plug off
completely.  All five, in one recent case.
