Ferrea Ford BOSS 302/351 C/429 1.8in 11/32 5.16in 12 Deg S-Flo +.100 Comp Plus Exh Valve - Set of 8

These Ferrea Comp Plus exhaust valves are built with a specific 1.8-inch face diameter and a 5.16-inch overall length, designed to fit Ford BOSS 302, 351 Cleveland, and 429 engines. The 11/32-inch stem size is a common specification for these performance Ford V8s, ensuring proper fitment within the valve guides.

Ferrea uses high-quality materials for their Comp Plus line, and these exhaust valves are no exception. They feature a hardened face and stem for improved durability under high temperatures and stress, which is crucial for performance applications. The valves are also +.100 inch longer than stock, which can be beneficial when working with modified cylinder heads or camshafts to achieve optimal valve lift and piston-to-valve clearance. The 12-degree sealing angle on the valve face helps ensure a solid seal against the valve seat.

This set includes eight valves, enough for a complete V8 engine. When rebuilding or modifying your Ford performance engine, using well-built valves like these from Ferrea is important for reliable operation and performance.
