SBC B/R 1.940in Intake Valves

The SBC B/R 1.940in Intake Valves from Manley are essential for small-block Chevrolet engine builders seeking significant performance enhancements. These precision-engineered intake valves cater to builders and enthusiasts who prioritize reliability and superior flow characteristics, ensuring they meet or exceed OEM specifications in high-RPM applications. Whether for street performance or competition-grade engines, these valves are designed for optimal combustion chamber sealing and fuel charge delivery.

Featuring a 1.940-inch head diameter, these valves strike a balance between maximum flow area and compatibility with both traditional and modern SBC cylinder heads. The manufacturing process guarantees tight tolerances on the valve stem and head interface, which minimizes seat wear and prolongs service intervals, even under high-load conditions. The B/R designation indicates a blunt-nose, radiused stem design that enhances durability and mitigates micro-welding risks during valve seat contact, particularly in forced-induction or nitrous applications.

Engine builders upgrading complete valve train assemblies on small-block Chevrolet platforms, including 350ci, 383ci, and stroker variants, will find these intake valves to be an excellent choice. Their design and engineering make them suitable for various applications, including street performance and marine use. With these valves, builders can expect improved performance and reliability in their engine builds.
