    Not sure I understand what you are looking at. Here's the core plugs in my 304.

    I'm gonna throw out a possibility. An old steel core plug got tapped into the head and left there.

    Another option could be pieces of a small block heater, but being in the head doesn't make that much of a reality.

    To my knowledge, there shouldn't be anything in there, so, if possible, it should be removed.
