Ferrea Chevrolet SB 1.6in 5/16in 5.450in 14 Deg Flo Hi-Temp +.500 Comp Plus Exhaust Valve - Set of 8

This set includes eight Ferrea Comp Plus exhaust valves, each measuring 1.6 inches across the head, with a 5/16-inch stem and a total length of 5.450 inches. These valves are specifically designed for Chevrolet Small Block engines and feature a 14-degree Flo head profile, intended to improve airflow into the combustion chamber.

Ferrea builds these valves with high-temperature alloys, making them suitable for demanding engine builds where heat management is critical. The Comp Plus designation indicates a specific design intended for improved performance and durability under stress. The valves are also +.500 inches longer than standard, which can be useful for certain cylinder head modifications or camshaft applications where valve lift or piston-to-valve clearance needs adjustment. This extra length requires careful consideration during installation to ensure proper geometry and clearance.
