Manley SBC S/D 1.600in Exhaust Valves 11865-8

Exhaust valves are mission-critical components that endure extreme heat and pressure cycles—failure here means catastrophic engine damage and lost race time. Manley's Severe Duty specification delivers the reliability and thermal stability needed for high-RPM, high-boost applications where factory valves simply won't survive. This set of eight stainless steel valves gives you the durability to push hard lap after lap without compromise.

Built from premium stainless material, these valves resist corrosion and maintain their structural integrity under the punishing conditions of forced induction and extended high-load operation. Whether you're running a street/strip SBC or a dedicated race engine, upgrading to Severe Duty valves eliminates a common failure point and lets you focus on tuning power, not chasing gremlins.
