LS7 E/D 1.615 Exhaust Valves

The LS7 E/D 1.615 Exhaust Valves by MANLEY are precision-engineered components designed for high-performance LS7 engine builds that demand reliability at extreme RPM and cylinder pressures. These exhaust valves are ideal for serious enthusiasts, race teams, and engine builders who prioritize quality in assembling or rebuilding a legendary 7.0L naturally aspirated powerplant.

Engineered with a 1.615-inch head diameter, these valves optimize the LS7's massive displacement and breathing characteristics, enhancing exhaust scavenging and thermal management compared to OEM specifications. The design allows for increased valve overlap and flow efficiency while accommodating the tight tolerances and aggressive valve seat angles that LS7 cylinder heads require. Manufactured from premium materials, each valve is subjected to rigorous quality control to handle extreme thermal cycling and combustion pressures.

LS7 engine builders, street/strip enthusiasts, and race teams preparing engines for sustained high performance will find these valves indispensable. The E/D designation reflects exhaust design parameters refined through decades of MANLEY's motorsports engineering expertise, making them a top choice for maximizing horsepower and torque while maintaining valve train integrity.
