WTB; Aluminum Head Core Plugs
 

I'm trying to locate a couple of the core plugs that go in the end of 3919842 aluminum heads. These plugs are made of aluminum and are different than the steel head ones. They are only present in the closed chamber heads, not the open chamber 3946074 alum head. Thanks!

Some of the electrical boxes use aluminum pipe plugs. Might check with an industrial electrical supply house.
