It has nothing to do with heat build up and everything to do with valves, cylinders and other moving parts. They are designed to move at a certain maximum speed and if you exceed that by to much even briefly things start to hit each other. This is what causes damage in an extreme over rev.
Again, you are not going to cause any damage at a coupe of hundred over since redline is a design spec not an absolute.

Got an example of someone over-revving a motor through missed gear selection for a second while not under load (accelerating) and causing valve float interference or piston/rod force related failure or friction/heat bearing/piston ring failure?
