SBC B/P 1.600in Exhaust Valves

The SBC B/P 1.600in Exhaust Valves by Manley are designed for serious small-block Chevrolet builders who require precision flow characteristics and durability under extreme combustion pressures. These valves are ideal for high-performance engine builds, whether for naturally aspirated street engines or forced-induction competition platforms.

Manley's 1.600-inch exhaust valve specification is the industry standard for small-block Chevrolet heads, providing optimal head flow without the need for extensive porting or CNC modifications. Manufactured from premium stainless steel, these valves feature precisely controlled stem diameters and face angles, ensuring consistent sealing and extended valve life, especially under high-RPM operation.

These exhaust valves are essential for any SBC build aiming for reliability above 6,500 RPM or operating in forced-induction environments. Their design supports excellent sealing geometry and heat transfer characteristics, making them compatible with both stock and aftermarket cylinder head castings.
