When you think about it for a minute Jay, it makes sense that the
cylinderheads cannot overheat when running lean of peak: There isn't
enough fuel in the mixture to overheat them.

???

I can easily get my EGTs over 1600 degrees, and my CHTs near (or over) 400
degrees by over-leaning. At some temperature (and I don't know what it is)
doesn't aluminum start to weaken?
