Kurt's Marine carries an assortment of Manley intake and exhaust valves, valvetrain components, and tools. Custom valves are also available from Manley. All Race Flo valves feature a hardened tip above the keeper groove to prevent wear from the rocker arm and are necked down in the combustion chamber area for improved flow and slightly reduced weight. Lash caps and guide plates from Manley are also available at Kurt's Marine
