A water wetter helps but Anti freeze actually degrades the rate at which water can pull the heat out of the head Propylene Glycol is the worst! Its like trying to cool an engine with molasses. If you have to run antifreeze run the Ethylene Glycol and run it as low a percentage as possible.

Obviously this is about strictly a drag race engine. Road race, asphalt oval tracks and even some drag strips have banned "Ethylene Glycol" because it is so difficult to clean-up after it gets on the racing surface so, a lot of dual-purpose cars in the northern states use Propylene Glycol, (Siera), because those cars see freezing weather sometimes.

Even is the southern states there were a multitude of broken engine blocks this year from freezing because racers did not drain the water. The race cars were stored in their trailer which were not heated and freezing temperatures for week did the damage.
