BBF C/6 1.655in Exhaust Valve

The BBF C/6 1.655in Exhaust Valve from FERREA is a precision-engineered cylinder head component designed for high-performance Ford FE-Series engine builds and restorations. This stainless steel exhaust valve serves as a critical control point in the combustion cycle, managing the precise timing and flow of spent gases from the cylinders into the exhaust manifold. Built to OEM specifications, this valve is essential for engine builders, performance technicians, and classic car enthusiasts seeking reliable valve train operation and longevity.

Manufactured in FERREA's 6000 Series stainless steel, the BBF C/6 1.655in Exhaust Valve features a 1.655-inch head diameter optimized for gas flow dynamics while maintaining structural integrity under extreme combustion temperatures. The 3/8-inch valve stem diameter provides consistent contact with rocker arms and lifters, while the 5.435-inch overall length ensures proper engagement with the valve guide and spring retainers. Stainless steel construction resists corrosion and thermal fatigue, critical factors in exhaust valve durability where temperatures regularly exceed 1,200 degrees Fahrenheit during operation.

This exhaust valve is purpose-built for Ford FE-Series engines, including iconic models from 1958 through 1976 such as the 390, 406, 427, and 455 cubic-inch variants. It serves both OEM replacement and performance upgrade applications, particularly in muscle car restoration, street/strip builds, and vintage racing engines where original valve materials no longer meet modern durability demands. Installation requires proper valve seat preparation and spring pressure verification to ensure correct seating and optimal combustion chamber sealing, making professional installation recommended for optimal engine performance and reliability.
