I'm using a piece of rectangular steel bar stock instead of a rocker arm shaft to mount the roller rockers. The spacing from the rocker arm pivot to the valve stem is set by the length of the long end of the rocker, and the pushrod hole in the cylinder head is slotted to allow a slight tilt of the pushrod to align with the short side of the rocker. Pushrods are custom made- - - -3/8" seamless stainless steel thick wall tubing with ball ends to match the sockets in the lifters and rockers. Valve lash is adjusted like any other stud mounted rocker, with long nuts and Allen set screws. If I can figure out how to add photos to this site I'll post some pictures.
