About This Product
These Manley Severe Duty intake valves are a premium choice for 1957 to 1969 Sportster models. Sold as a pair, they are standard-size replacements for OEM 18070-58, featuring a 1.813-inch head diameter and a .309-inch stem. Manley uses a high-temperature stainless alloy and a swirl-polished finish to ensure maximum flow and durability. The chrome-plated stems provide excellent wear resistance. These valves are significantly lighter than the original factory components, which helps keep the valvetrain stable and responsive even at high engine speeds. They are a perfect upgrade for any early Ironhead Sportster restoration or performance engine project.
Manufacturer part number: 99034-2.
