My machine shop did some sort of test (hardness or Brinnel (sp)) to determine what gear came with my Mallory. I had already bought a steel gear from Ford just to be sure but it turned out the gear supplied with my Mallory was a harder steel than the Ford.
Point is, take the gear to a good machine shop. They should be able to determine if the gear you already have is steel or not.

Perhaps a bronze gear should enter this topic.
My performance issues disappeared when this type gear was installed.
