CORE PLUG PULLING
Some core plugs are notoriously tricky to remove. One example, that I see a lot of, is the deep plugs used in the back two positions of big block Chryslers where the cylinder wall is close to the plug hole. I simply tack weld a nut to the core plug. Then I can use a slide hammer to pull them out.
