We also love pics - condition not important. Your 1986 Power Ram 50 uses a hydraulic lash adjustor style head. Clearwater head, CNS, and a few others sell a complete head with valves, springs, rocker assembly with lash adjusters ready to bolt on for in the 400 - 500 range. Be sure to buy new head bolts, as these head bolts are torque to yield, and cannot be reused. Use a quality gasket set, and retorque after 500 miles and you will be set.
