If you operate your engine without it being warm, then you are really putting excessive wear on the head, pistons, and rings.

Yes. That's a good point, but what I'm saying is that on the engines I've run by the time the oil is warmed up enough to rev up the engine the cylinder head temps are good to go. That's all.
