The LS7 R/M 1.615 Exhaust Valves by MANLEY are designed for serious LS7 engine builders and high-performance enthusiasts who require reliable, race-proven components. These valves are specifically engineered to withstand the extreme demands of modified LS7 powerplants, where factory exhaust valves may not perform adequately under high-stress conditions such as boost or nitrous applications.
With a head diameter of 1.615 inches, these valves optimize flow characteristics while maintaining structural integrity under high combustion pressures. The R/M designation indicates that they are built to race and marine specifications, featuring high-quality alloy steel construction and precision-honed seats to minimize exhaust gas leakage, which is essential for maximizing scavenging efficiency.
These exhaust valves are ideal for various LS7 engine applications, including fuel-injected street cars and full-race powerplants, where factory components may fall short. When upgrading your valve train, consider pairing these valves with quality springs and retainers to ensure optimal performance and durability.
