Ferrea Chevy SB 1.625in 11/32 5.060in 20 Deg Tulip S-Flo +.150 Comp Plus Exhaust Valve - Set of 8

These Ferrea Comp Plus exhaust valves feature a 1.625-inch tulip head diameter and a 5.060-inch overall length, designed for Chevy small block engines. The 20-degree seat angle and S-Flo design help improve airflow into the cylinder, which can make a notable difference in engine performance. The +.150 compression plus design means these valves are slightly longer than stock, allowing for more compression if you're rebuilding your top end and need to adjust piston-to-valve clearance or valve spring installed height.

Built with high-quality steel, these valves are made to withstand the heat and stress of performance engine operation. The S-Flo design is a unique feature that helps reduce valve float at higher RPMs by optimizing the flow path. This set includes eight valves, enough for a complete V8 engine rebuild. They are intended for performance applications where improved airflow and durability are key.
