Around 200 degrees running temperature is normal with a maximum of around 230 degrees. Beyond that you're in a danger zone.

The temp always goes up after you shut the engine off as there is no fan in operation, no water circulation and no heat is being dissipated so the heat sits there and the temperature rises for a bit until it naturally dissipates.

Since everything else in the cooling system is new and the temp only rises at idle it would be logical to conclude that you most likely need a new fan clutch unit. A Motorcraft unit is fine unless you want to go with an electric fan set-up. Your choice.
