Richen mixture to reduce cylinder head temp?

I am running a supercharged 3.6, and have a question.

Does richen up the mixture (part throttle and cruise) reduces cylinder head temperature? If so, how much?

Right now, it's 14.7 as controlled by the O2 sensor in closed loop. Wondering if I richen it up to about 13.5 would that reduce cht and probably prevent detonations too.

WOT is at/below 12 AFR.
