Ferrea Chevy/Chry/Ford SB 1.6in 11/32in 5.34in 0.29in 15 Deg +.400 Ti Comp Exhaust Valve - Set of 8

This set includes eight Ferrea Competition Plus exhaust valves, specifically designed for Chevy, Chrysler, and Ford small block V8 engines. Each valve features a 1.6-inch diameter head and a 5.34-inch overall length, with a 0.29-inch stem diameter and a 15-degree seat angle. These valves are constructed from titanium, offering a significant weight advantage over traditional steel valves, which can help your engine rev more freely and reduce stress on the valvetrain components. The +.400 sizing indicates these are intended for engines that have been bored out by 0.400 inches, ensuring a proper fit in modified cylinder heads.

Ferrea is known for producing well-built internal engine components, and these Competition Plus valves are a popular choice for builders looking to improve performance in their V8 engines. The titanium construction not only reduces mass but also offers good resistance to heat and wear, crucial for exhaust valves that endure high temperatures. The 15-degree seat angle is a standard specification that works with most common cylinder head designs. When rebuilding or modifying your engine's top end, using high-quality valves like these can make a notable difference in reliability and performance.

Installing these valves is part of a larger engine build process, typically involving cylinder head disassembly and reassembly. It's important to ensure your cylinder heads are properly machined to accept the +.400 sizing and that the valve seats are correctly cut for the 15-degree angle. Using the correct valve springs and retainers that match the valve's weight and operating RPM is also critical for optimal performance and longevity. Refer to your engine build specifications and manufacturer's instructions for proper installation procedures.
