Actually, this wire is left over from the sandcore layup process used to make the heads. The wire was used to hold the cores tightly together so the pour would not seperate them. Then the sand is tumbled out of the raw casting before the machining that finishes the head. The wire stays behind, however, since it is sometimes trapped by the iron. Doesn't hurt anything.
