Ferrea Chevy/Chry/Ford SB 2.1in 5/16in 5.45in 0.29in 12 Deg +.500 Ti Comp Intake Valve - Set of 8

These Ferrea Comp intake valves are made from titanium, a material chosen for its strength and light weight, which is crucial for high-performance engine builds. Each valve measures 2.1 inches in diameter with a 5/16 inch stem and a total length of 5.45 inches. The +.500 dimension indicates they are 0.500 inches longer than a standard valve, which is important when working with modified cylinder heads or camshafts that require increased valve lift or different geometry. The 12-degree seat angle is a common specification for many performance applications, ensuring a good seal against the valve seat.

The titanium construction significantly reduces the mass at the end of the valve train compared to steel valves. This lower reciprocating weight allows the engine to rev more freely and reduces stress on components like the camshaft, lifters, and valve springs, especially at higher RPMs. Ferrea is known for producing well-built engine components, and these valves are designed to handle the demands of performance engines where stock parts might not be sufficient. The set includes 8 valves, ready for installation in your Chevy, Chrysler, or Ford Small Block engine.

When installing these valves, it's important to ensure your cylinder heads are prepared to accept the +.500 length, potentially requiring modifications to the valve guides or piston valve reliefs. Always refer to the manufacturer's installation instructions for specific details regarding compatibility and proper setup with your chosen camshaft and cylinder head combination.
