Nice!!! Found something I was looking for. A graph for 1340 that shows how spark advance affects CHT. Plus many other data.

This was the second method described by P&W patent to reduce head temperatures (in addition to using rich mixture). They experimented with a thermostat that was connected to magnetos to automatically control spark advance. But in this case we have a manual lever for that.
