In the past, we've established that the OLD IRON in the blocks & head are just a "FACTORY" producing RUST FLAKES. They end up stuck in the top of the radiator & lessen the efficiency of the radiator. Back flushing the system once or twice a year helps.
Another culprit is a system filled with greasy scum. That can be cleaned with your favorite, NON-FOAMING detergent. T.S.P. or even dishwasher soap will work.
Overheating is NOT a problem, with a decent radiator & NO head gasket combustion leaks. Combustion leaks can even be detected, by smelling the radiator filler neck!
Hope this helps.
