Description

The BBC SD 1.900 Exhaust Valves by Manley are engineered for severe-duty applications in big-block Chevrolet engines, providing reliability under extreme conditions. This set of eight stainless steel exhaust valves features a 1.900-inch head and 11/32-inch valve stem, making them suitable for high-RPM performance and various engine configurations.

Constructed from premium stainless steel, these valves offer superior corrosion resistance and fatigue strength compared to standard cast-iron alternatives. The 6.380-inch overall length (OAL) integrates seamlessly into big-block Chevy cylinder heads, while the Severe Duty (SD) designation indicates enhanced durability and optimized head geometry for sustained high-performance operation.

These valves are ideal for big-block Chevy enthusiasts looking to enhance their engine's performance, whether for racing, street applications, or modified builds. They address the critical need for thermal stability and sealing under load, making them a valuable addition to any performance engine setup.
