The metal piece that is somewhat molded to the exhaust manifold that protects the plug wires from the manifold heat. Can that piece be removed without taking the exhaust manifolds off? I wanted to repaint mine or clean it up if it is galvanized. Thanks for any ideas.

Yes, there are small bolts under the manifold that you can loosen to get them out. One or two have small screws holding them together, some are welded onto the stalk. they are galvanized.
