Tom: these plates were factory issue for the repair of worn out push rod slots in the heads.They were sold "each" . Each plate accomodated two pushrods--an intake and exhaust. The guide plate was ingenious in that no machining was necessary. The installation procedure was to remove a pair of rockers,drop the plate over the studs and replace the rockers. Done! The pushrod side was slightly long (some thought it was a mistake) and extended over to the valve cover gasket. the gasket held the pushrod side in place and the stud side rode against the underside of the rocker arm. Brilliant !
I just looked in Pete's book and the 9777594 looks similar to the SD but without the hold down hole
