Ferrea Chevy/Chry/Ford SB 2.125in 5/16in 5.55in 12 Deg +.600 Titanium Comp Intake Valve - Set of 8

These Ferrea Comp Intake Valves are made from a strong titanium alloy, chosen for its lightweight properties and durability under high heat. Each valve features a 2.125-inch head diameter and a 5/16-inch stem, designed to fit a wide range of Chevy, Chrysler, and Ford Small Block engines. The 12-degree face angle is optimized for sealing in performance cylinder heads.

The overall length of these valves is 5.55 inches, with an extended +.600 inches over standard length, which is crucial for achieving proper valve train geometry when using high-lift camshafts and aftermarket cylinder heads. This extended length helps ensure the valve is not only sealing correctly but also that the rocker arm geometry remains within optimal parameters, preventing premature wear on valve train components. The titanium construction significantly reduces valve float at high RPMs compared to heavier steel valves, allowing your engine to rev more freely and safely.

This set includes eight intake valves, enough for a complete V8 engine build. Ferrea is well-known for producing high-performance internal engine components, and these valves are a solid option for anyone rebuilding or upgrading a performance Small Block engine. When installing, pay close attention to valve spring pressures and piston-to-valve clearance, especially with the extended length and high-lift camshafts.
