Folks, having just responded to a thread on oil temps, I realised this is a genuine serious thing, but nothing at all as important as CHT.
Now if you have a Rotax....or liquid cooled heads you need to think carefully about different parameters. Jabiru heads, the numbers should be a lot lower also.
But the bulk are Lycoming and TCM I would imagine.
CHT should be set green up to 380F, yellow from 380 to 400, and 400 and above in RED with alarm set for 400 or more.
And if anyone wants to debate this WITHOUT thinking with their brain first, they will get a fair dose of "keyboard lashing" from me.
Just think about for a while
....I know someone is going to be tempted to say 450 or 500F 
If you cant climb and cruise under 380 F there is a baffling problem, or you have a good dose of detonation going on, and if you do not, you are not far from creating some if you are not careful.
This thread should be posted as a STICKY for all to read.
