About This Product
Manley Severe Duty exhaust valves suit 1957 to 1985 Sportster engines. Sold as a pair. They have a 1.563-inch head diameter and a .3385-inch stem. They replace OEM 18036-80. The heads are swirl-polished stainless and the stems are chrome-plated. They run up to 30% lighter than stock valves. That keeps the valve train stable at higher RPM. Fit them with new guides and check the stem clearance before lapping them in.
Manufacturer part number: 99000-2.
