Chevrolet installed on some of their V8 engines "lifting rings" held onto the head by 2 bolts. Each had a 3/4 or 1" hole in the vertical part of the "ring" and I believe this was used by the factory during installation of the engine and simply left on the engine instead of taking time to remove. I need 2 of these things and would be grateful to anyone out there willing to be of help in this matter. Jim @
