Ferrea Chevy/Chry/Ford SB 2.1in 5/16in 5.55in 0.29in 12 Deg +.600 Ti Comp Intake Valve - Set of 8

Ferrea is well-known for making high-performance valvetrain components, and these titanium composite intake valves are a prime example of their work. If you're building or rebuilding a Chevy, Chrysler, or Ford small block engine and need valves that can handle serious stress, these are a solid option. They're designed to be a direct replacement for your stock valves, but with a significant upgrade in material and performance.

What makes these valves stand out is their titanium composite construction. This material is chosen for its excellent strength-to-weight ratio, meaning these valves are both strong enough to withstand high cylinder pressures and high temperatures, yet light enough to reduce valvetrain stress. This can lead to improved engine response and durability under demanding conditions. The 2.1-inch face diameter is larger than stock on many small block applications, which helps to increase airflow into the combustion chamber, potentially boosting horsepower and torque. The 5/16-inch stem diameter is standard for many performance applications, ensuring compatibility with a wide range of valve springs and retainers. These valves are also +.600 inches longer than standard, which is often necessary when using aftermarket cylinder heads or camshafts that alter valve train geometry. The 12-degree seat angle is a common performance angle that can improve sealing and airflow.

This set includes eight intake valves, enough for a complete V8 engine. When installing these, pay close attention to the manufacturer's recommendations for valve spring pressure and piston-to-valve clearance, especially given the larger valve size and extended length. Ensuring proper clearance is critical to prevent catastrophic engine damage.
