Ferrea Chevrolet BB 1.9in 11/32in 5.425in 18 Deg Tulip Flo +.100 Comp Plus Exhaust Valve - Set of 8

These Ferrea Comp Plus exhaust valves are built with a specific 18-degree tulip face angle, a design choice that helps improve airflow into the cylinder. Each valve measures 1.9 inches across the head and has a 5.425-inch overall length, with a 11/32-inch stem diameter. This set includes eight valves, intended for Chevrolet Big Block engines that have been modified for improved performance.

Ferrea uses high-grade materials for their Comp Plus line, and these exhaust valves are no exception. They are constructed from a strong, heat-resistant alloy designed to withstand the demanding conditions inside a performance engine. The +.100 Comp Plus designation indicates a slightly larger valve head diameter compared to standard, which can contribute to better cylinder filling and overall power output when properly matched with other engine components. This attention to material and design detail means you're getting a well-built part that can handle the stress of high-RPM operation.

When rebuilding or upgrading your Chevrolet Big Block's top end, using valves like these from Ferrea can make a notable difference. Ensure your valve guides and seals are in good condition, as these valves are designed for a direct fit into compatible applications. Always refer to your engine build specifications to confirm these dimensions are appropriate for your specific setup.
