Whatever the case, I know mine has seen and survived sustained 180 deg C head temperatures... It did not run right that hot (vapour locking) but it did not hurt it either.
That't amazing, I don't think many engines would survive under the same circumstances.
I have great respect for good engineering, I remember reports of this engine operating regularly well past the manufacturer's max. RPM's in a GAUI NX4 with no issues.
Great pity this engine is no longer available...
