Timing + = higher engine temps, right?

I talked to an engine builder at a street rod show and I got some confusing information, now I need to confirm.

All else being equal, more timing will yield higher engine temperatures right?

This engine builder told me the opposite, that retarded timing (lower) would cause higher temps.

Which is right?

I believe the reason that it would run hotter retarded is that the engine is having to work harder to achieve the same power - less efficient.

Advanced timing will cause higher combustion chamber temperatures. Taking the timing either way from ideal will cause the engine to generate more heat because it's using fuel less efficiently. Withing reason the temperature won't change because the thermostat will control it.

REALLY confused now?
