Ferrea Chevrolet LS1 1.55in 0.313in 4.915in 15 Deg Flo Rad Grv 6000 Series Exhaust Valve - Set of 8

Ferrea is well-known for making high-performance valvetrain components, and these 6000 Series exhaust valves are a prime example of their work for Chevrolet LS1 engines. If you're rebuilding or upgrading your LS1's top end, these valves are built to handle the demands of performance applications. They feature a 1.55-inch head diameter and a 0.313-inch stem, with a length of 4.915 inches, designed to fit precisely within the LS1 cylinder head. The 15-degree seat angle is a common specification for these engines, ensuring proper sealing.

These valves are constructed from a durable material, chosen for its ability to withstand the high temperatures and stresses found in performance LS1 engines. The 'Flo Rad Grv' design indicates a specific groove pattern that can aid in lubrication and reduce valve stem wear over time, a detail that shows Ferrea's attention to longevity in their performance parts. This set includes eight valves, enough for a complete set of exhaust valves for a standard V8 LS1 engine. They are a solid option for anyone looking to ensure their engine's valvetrain is up to the task of improved performance or a reliable rebuild.
