BBM C/6 1.810in Exhaust Valve

The BBM C/6 1.810in Exhaust Valve from FERREA is a precision-engineered component built for high-performance engine applications where OEM valves fall short. Whether you're building a street machine, preparing for track duty, or restoring a classic with modern power goals, this exhaust valve delivers the flow characteristics and durability demanded by serious enthusiasts and tuners. Designed to maximize scavenging efficiency and reduce exhaust restriction, it's the kind of upgrade that separates a mediocre build from a genuinely responsive engine.

FERREA exhaust valves are manufactured to exacting tolerances using premium materials engineered to withstand sustained high-temperature cycles and aggressive valve spring pressures. The 1.810-inch head diameter on this BBM C/6 specification is optimized for cylinder head porting that flows toward the mid to upper-RPM range, making it ideal for naturally aspirated builds targeting responsive mid-range torque and top-end horsepower. The lightweight design reduces reciprocating mass, lowering stress on valve train components and allowing higher RPM capability without sacrificing reliability or component longevity.

This exhaust valve suits engine builders working with small-block platforms, particularly those running aftermarket heads with matching bowl work and port sizing. Installation requires proper valve seat work and spring pressure verification to ensure the valve seats correctly and operates within design parameters. Pairing this valve with quality intake valves, hardened seats, and a balanced valve train setup ensures years of reliable performance whether your application is street-driven daily or weekend-only high-RPM duty. Confirm head compatibility and valve seat specifications with your machine shop or cylinder head manufacturer before ordering.
