Can a cylinder heat up that much on takeoff? I have never looked.

yes. My 140 gets pretty close to 500 degrees during climbout
(500 is redline for my engine).

Are takeoff and climbout the same thing?

is the distinction important?

Well, yes. Beech recommends 105 for climb out, but better is 120 for better
visibility and MUCH BETTER COOLING. Rate of climb (after obstacle clearance)
is only marginally less (about 1025 fpm vs 1075 in my F33A).
