Ferrea Chevrolet SB 1.625in 5/16 5.450in 0.25in 14 Deg S-Flo +.500 Comp Plus Exhaust Valve- Set of 8

These Ferrea Comp Plus exhaust valves are built with a specific 14-degree S-Flo angle, which helps improve airflow into the cylinder. They measure 1.625 inches in diameter and have a 5/16-inch stem, with an overall length of 5.450 inches. The +.500 Comp Plus design means they are 0.500 inches longer than stock, giving you more options when setting up your valvetrain, especially if you've modified your cylinder heads or are using different valve springs.

Ferrea uses high-quality steel for these valves, chosen for its ability to withstand the high temperatures and pressures found in performance engines. The S-Flo design is a notable feature, as it creates a smoother path for the air-fuel mixture to enter the combustion chamber, potentially leading to better engine breathing and more power. This set includes eight valves, enough for a complete V8 engine.
