Ferrea Chevy/Chry/Ford SB 1.625in 11/32in 5.55in 0.29in 15 Deg +.600 Ti Comp Exhaust Valve- Set of 8

If you're rebuilding the top end of your Chevy, Chrysler, or Ford small block engine, these Ferrea F1602 competition exhaust valves are a solid choice. They're built for performance applications where reliability and durability are key. These valves measure 1.625 inches in diameter with a 11/32 inch stem, and a overall length of 5.55 inches. The valve face has a 0.29 inch margin and a 15-degree seat angle, designed to work with many common cylinder head configurations. The +.600 dimension indicates they are 0.600 inches longer than a standard valve, which is often needed for specific camshaft profiles or cylinder head porting.

Ferrea uses high-quality titanium for these valves, which offers a notable advantage in reducing weight compared to traditional steel valves. This lower mass means less stress on your valvetrain components, allowing for higher RPMs and improved engine response. The titanium construction also offers excellent resistance to heat and wear, crucial for exhaust valves that endure the hottest conditions in the combustion chamber. This set includes eight valves, making it suitable for V8 engines. They are well-built to handle the demands of performance builds, whether for street use or the track.

When installing these valves, ensure your cylinder heads are properly prepared and that the valve guides are within specification for the 11/32 inch stem diameter. It's also important to confirm that the +.600 length is compatible with your piston-to-valve clearance requirements, especially when using aggressive camshafts. These valves are a critical component for achieving optimal performance and longevity in your engine build.
