Ferrea Chevy/Chry/Ford SB 1.65in 11/32in 5.45in 0.29in 15 Deg +.500 Ti Comp Exhaust Valve - Set of 8

Ferrea is well-known for making high-performance valvetrain components, and this set of competition exhaust valves for Chevy, Chrysler, and Ford small block engines is a prime example of their work. These valves are built to handle the demands of serious engine builds where reliability and performance are critical. They feature a titanium construction, which is significantly lighter than traditional steel valves, helping to reduce valvetrain stress and allow for higher RPMs. The specific dimensions—a 1.65-inch head diameter, 11/32-inch stem diameter, and a 5.45-inch overall length—are designed to fit a range of popular SB applications.

The material choice here is key. Titanium offers excellent strength-to-weight ratio and good heat resistance, making it ideal for exhaust valves that see extreme temperatures. These valves are also +.500 inch oversized on the stem, which is important to note for your build. This means they are intended for cylinder heads that have been machined to accept a larger stem diameter, often done to improve sealing or accommodate specific guide setups. The 15-degree valve seat angle is a standard specification that ensures compatibility with most common cylinder head designs.

This set includes eight valves, enough for a complete V8 engine. When you're building an engine that needs to perform at its best, components like these Ferrea valves are crucial for achieving optimal airflow and durability under high stress. They are a solid option for anyone looking to maximize the potential of their SB engine build.
