Can an overheated aluminum engine head be heat treated (with weights on
it to keep it flat) to bring back its temper and hardness?

If it's going to warp there is nothing you can do to prevent it. It's all
about internal stresses in the metal. If such weight keeps it flat, it will
warp upon removal of the weight.
