Here is my Mark II style..... It works on Edelbrock Performers, and Stock Cast iron. No reason it couldn't be fabricated to work with most all manifolds, but.... I mocked it up on the Ford cast iron manifold, but once it was made, it interfered with the larger runners on my new Blue Thunder manifold.
That's why I went to the Mark III design.
