As has been already stated, don't heat it. Spring steel is a hardenable type of carbon steel that is formed cold. The cold forming, winding if coil, bending in a jig if a leaf, introduces stresses in the steel that give it "memory" when it is later flexed. It wants to go back to the original shape it was formed into. Heating a spring relieves those stresses, basically annealing (making soft) the metal. The result would be that the spring will bend at the annealed point, and stay bent.
Be careful about bending that spring. Applying too much force can break it, as there is a certain amount of brittleness in all springs. Too, the older and more used a spring is, they tend to do one of two things: either get soft (heat from flexing over time anneals them), or the metal fractures.
