Description
LS7 engines demand exhaust valves engineered for sustained high-RPM performance and thermal cycling. These Manley R/M valves are precision-manufactured to handle the extreme demands of forced-induction and nitrous applications while maintaining precise sealing integrity. OEM valves simply won’t survive aggressive tuning—upgrade to components built for power.
