BBM C/6 1.810 Exhaust Valves

The FERREA BBM C/6 1.810 Exhaust Valves are premium stainless steel engine components engineered for Mopar B and RB-series big-block engines. This set of eight valves is designed for serious enthusiasts and mechanics rebuilding high-performance or stock-replacement cylinder heads where precision and durability are non-negotiable. Exhaust valves endure extreme thermal and mechanical stress—cycling through combustion events at sustained temperatures exceeding 1,200°F while sealing combustion pressure—making quality material and manufacturing critical to engine longevity and reliability.

Each valve features a 1.810-inch head diameter paired with an 11/32-inch stem diameter and extends 4.930 inches in overall length, matching OEM specifications for Mopar B and RB-block applications. The stainless steel construction resists corrosion and maintains structural integrity under repeated thermal cycling, critical for engines running aggressive fuel mixtures or extended high-RPM operation. FERREA's 6000 series valves employ superior metallurgy and precision grinding to ensure tight seat contact, minimize leakage, and reduce emissions—properties that directly impact compression, thermal efficiency, and combustion chamber scavenging.

Engine builders, professional mechanics, and vintage Mopar restorationists rely on these valves for complete head overhauls, performance upgrades, and factory-specification rebuilds. Installation requires proper valve seat machining, precise height measurement, and correct installed spring pressure to prevent valve float or seal recession. This eight-piece set covers the full exhaust valve complement for one complete engine, simplifying sourcing and ensuring consistent valve quality across all cylinders for balanced combustion and stable idle.
