About This Product
Manley Severe Duty exhaust valves fit 1948 to 1983 Panhead and Shovelhead engines. Sold as a pair. They have a 1.75-inch head diameter and a .3745-inch stem. They replace OEM 18089-80. The stainless heads are swirl-polished and the stems are chrome-plated. They weigh less than stock valves. That helps prevent valve float when the engine is worked hard. Fit them with new guides and check the guide clearance before final assembly.
Manufacturer part number: 99011-2.
Fitment
48-83 Panhead; Shovelhead
