Ferrea Ford BOSS 302/351 C/429 1.77in 5.165in 14 Deg S-Flo +.100 Comp Plus Exhaust Valve - Set of 8

Starting with a 1.77-inch head diameter and a 5.165-inch overall length, these Ferrea Comp Plus exhaust valves are specifically made for Ford BOSS 302, 351 Cleveland, and 429 engines. The +.100 Comp Plus design means these valves are slightly longer than stock, which can be important when you're rebuilding the top end and need to achieve specific valve train geometry or piston-to-valve clearance. Ferrea is known for making well-built engine components, and these valves are no exception.

These valves feature a 14-degree S-Flo design, which helps improve airflow by reducing turbulence as the exhaust gases exit the cylinder. The material used is chosen for its strength and ability to withstand the high temperatures and pressures found in performance Ford V8s. If you're working on a performance build for your BOSS engine, these valves are a solid option to consider for improved breathing and durability.
