Comp rocker arms were made by Jim Dove. In fact, he made most of the aluminum rocker arms, no matter whose name was on the box. He had a heavy duty set-up available that he sold under his own name. They included end stands that tied into special head bolts for stability. The last time I talked to Ray Paquet, his attitude was to install the HD set-up and then forget it. They were his ultimate answer. (That's been several years ago, so I have no idea if the forgoing is true now.)
