Part is off a 1979 XR500 1979 - 1982 XR and XL 500 use the same gasket set. My guess is the head is the same for those models. Very little if any wear to rockers, or cam journals. The mount was almost cut completely off needs welded back up otherwise in great shape. The item "Honda XR500 / XL500 Cylinder Head Valve Rocker Cover 79-82" is in sale since Wednesday, May 20, 2020.
