If an engine gets up to 180c it is cooked no matter what coolant is running through the pipes.

At 180c your oil is going to cook off and the engine will blow.

That is along with the transmission fluid boiling, but you guys do not use automatic transmissions so I suppose you do not have that problem.

Back in the 1980s we used to have a problem called "flash overheating" where the high reving engines, especially the Toyotas of that era, would suddenly shoot up in temp and cook the oil to sludge. It was a combination of small radiators and poor oil performance.

It usually resulted in a rod going thorough the engine block. Oil technology had not caught up with the engine capabilities. You do not hear about it much any more. We now have better oils and recommended maintenance schedules are tighter.
