These oversized blank stem valves from AV&V are engineered for specialized Harley-Davidson engine projects where standard valve dimensions are insufficient. The stems are finished with a hard chrome layer over a centerless ground micro finish, promoting longevity and smooth operation. Designed for professional engine builders, these valves arrive with blank stems, requiring custom machining for key grooves. It is essential to use valve stem lash caps, as the tips are supplied unhardened to facilitate the customization process. By utilizing these high-flow blanks, builders can fine-tune the valvetrain geometry and port flow to extract the highest possible output from a custom V-Twin power plant.
