SBC R/F 1.940in Intake Valve

The MANLEY SBC R/F 1.940in Intake Valve is designed specifically for small-block Chevrolet engine builders and performance enthusiasts who require high-quality valve components for high-rpm applications. This intake valve is ideal for those assembling race engines, rebuilding strokers, or optimizing their SBC for competitive performance.

Engineered as a direct replacement for OEM applications, this valve maintains compatibility with performance cylinder head designs. The 1.940-inch face diameter is optimized for standard small-block Chevrolet head configurations, ensuring proper seating surface contact and consistent combustion chamber volumes. Manley valves are made from premium alloy materials that resist thermal fatigue, corrosion, and wear, which are crucial for high-performance applications.

Serious SBC builders, whether for street machines, bracket racing, or weekend projects, will appreciate the durability and performance of Manley's track-proven valve components. The R/F (rectangular face) design enhances seal integrity during compression and combustion cycles, leading to improved cylinder filling efficiency and predictable valve actuation timing.
