BBC R/F 1.880in Exhaust Valve

The BBC R/F 1.880in Exhaust Valve from Manley is a precision-engineered component designed for big block Chevy high-performance and racing applications. This stainless steel exhaust valve is built for engine builders and racers who demand reliability and consistent flow characteristics in extreme operating conditions. Whether you're assembling a street performance engine or preparing a dedicated race motor, this valve delivers the durability and thermal stability required for sustained power delivery.

Featuring a 1.880-inch head diameter and 0.372-inch valve stem, this Race Flo exhaust valve is optimized for maximum flow efficiency while maintaining structural integrity under high RPM loads. The 5.350-inch overall length ensures proper fitment within big block Chevy cylinder head configurations, and the stainless steel construction resists oxidation and corrosion from exhaust gas exposure. Manley's precision manufacturing and shot-peening process enhance fatigue resistance, making this valve suitable for turbocharged, supercharged, and naturally aspirated applications that demand extended valve life.

This exhaust valve is ideal for engine builders restoring or upgrading big block Chevy platforms, including applications in classic muscle cars, vintage race engines, and modern LS-adjacent big block builds. Proper valve seat preparation and correct spring pressure tuning are essential for optimal performance and longevity. Each valve is supplied individually, allowing builders to source complete valve sets with matching components. Installation requires precision machine work and professional guidance to ensure correct seating and clearance specifications.
