Ferrea Chevrolet SB 1.6in 7mm 5.55in 24 Deg Tulip Rad Grv +.600 Super Alloy Exhaust Valve - Set of 8

Ferrea is well-known for making high-performance engine components, and these exhaust valves are a prime example of their work. Designed for Chevrolet Small Block engines, these valves are built to handle the demands of performance builds. They feature a 1.6-inch diameter head and a 7mm stem, with a 24-degree tulip radius groove, and are +.600 inches longer than stock, making them suitable for specific head porting and camshaft applications.

Constructed from a super alloy, these valves offer improved resistance to heat and wear compared to standard materials. This makes them a solid option when you're rebuilding or upgrading the top end of your engine, especially if you plan on pushing the RPMs or running higher cylinder pressures. The +.600 inch length is a notable detail, often used in conjunction with specific cylinder head modifications to optimize valve lift and flow characteristics.

This set includes eight valves, enough for a complete V8 engine. When installing, ensure you're using components that match the valve stem diameter and length to avoid issues with valve guides and piston-to-valve clearance.
