GM LS7 S/D 1.615 Exhaust Valves

The MANLEY GM LS7 S/D 1.615 Exhaust Valves are severe duty performance components specifically engineered for General Motors LS-series engine platforms. This set of eight stainless steel exhaust valves is designed for high-performance applications, providing enhanced thermal resistance and durability in demanding engine environments.

Constructed from premium stainless steel, these valves are built to withstand extreme combustion pressures and temperatures, making them ideal for modified, turbocharged, and naturally aspirated LS engines. Each valve features a 1.615-inch head diameter, a 0.314-inch valve stem, and measures 5.230 inches in length, ensuring precise intake and exhaust flow geometry within the LS cylinder head casting.

These exhaust valves are particularly beneficial for LS engine builders and enthusiasts looking to upgrade cylinder head flow on stroker engines or those running high RPMs and increased boost pressures. Their severe duty rating indicates they are designed to endure the rigors of sustained high-performance operation, making them a reliable choice for both street and competition use.
