Ferrea Chevy/Chry/Ford SB 2.15in 11/32in 5.34in 0.29in 12 Deg +.400 Ti Comp Intake Valve - Set of 8

If you're building a high-performance small-block Chevy, Chrysler, or Ford engine, these Ferrea Competition Plus intake valves are a solid choice. This set includes eight valves, each measuring 2.15 inches in diameter with a 11/32-inch stem. They are designed to be 0.400 inches longer than stock, measuring 5.34 inches overall, which can be useful for specific camshaft profiles or cylinder head porting. The 12-degree swirl-polished face helps improve airflow into the combustion chamber.

Ferrea uses a high-quality titanium alloy for these valves, which offers a notable strength-to-weight advantage. This means the valves are strong enough to handle the stresses of high RPM and aggressive valve springs, yet they are lighter than traditional steel valves. This reduced mass at the valvetrain allows for better control at higher engine speeds, helping to prevent valve float and ensuring more consistent performance. The stem tip is also designed for positive locking retainers, and the overall construction is well-built for demanding applications.

When installing these valves, it's important to ensure your valve guides and seals are in good condition and compatible with the 11/32-inch stem diameter. Because these valves are longer than stock, you'll want to carefully check piston-to-valve clearance with your chosen camshaft and piston combination to avoid any interference. This attention to detail during installation is key to unlocking the full potential of these performance valves in your engine build.
