A properly lean mixture will also keep the engine cool, save lots of fuel, provide less "dirt" in the oil, cleaner spark plugs, smooth out the pressure in the combustion chamber, etc.
Supercharged, gas burning, 1000+ horse power radial engines during the golden age of air carrier transport didn't keep the engines cool by running richer. They'd never make it across the pond.
