SBC S/F 1.600in Exhaust Valves

The SBC S/F 1.600in Exhaust Valves from Manley are precision-engineered components designed for small-block Chevrolet engines requiring OEM-diameter replacement or high-performance bolt-in upgrades. These valves are essential for serious engine builders and mechanics who are restoring or modifying classic and contemporary SBC platforms.

Manley's exhaust valves feature a 1.600-inch head diameter, suitable for small-flow (S/F) cylinder heads. The valve stem is precision-ground to exact OEM tolerances, ensuring proper clearance in factory guide bores. Constructed from durable stainless steel or high-temperature alloy steel, these valves resist corrosion and maintain their shape under sustained exhaust heat cycles.

Engine builders favor Manley exhaust valves for SBC rebuilds, especially when OEM replacements are insufficient. These valves are designed to provide repeatable sealing performance across thousands of miles of operation, making them ideal for both street and competition applications.
