Ferrea Chevrolet SB 1.625in 5/16in 5.01in 12 Deg Flo Rad Grv +.100 6000 Series Exh Valve - Set of 8

These are Ferrea 6000 Series exhaust valves, designed for Chevrolet Small Block (SB) engines. This set includes eight valves, each featuring a 1.625-inch head diameter and a 5/16-inch stem. They are built with a specific profile and a 12-degree face angle, intended to help improve airflow into the cylinder. The valves are also +.100 inches longer than stock, which can be useful when working with modified cylinder heads or specific valvetrain setups.

Ferrea uses high-quality steel for their 6000 Series valves, known for their strength and durability under high temperatures and pressures common in performance engines. The Flo-Rad groove design is a notable feature that helps reduce valve weight and can contribute to improved airflow characteristics. These valves are a solid option for builders looking for well-made components to handle demanding engine builds where reliability and performance are key.

When installing these valves, remember they are +.100 inches longer than standard. This means you'll need to ensure your piston-to-valve clearance is checked carefully, and you may need to adjust your valvetrain geometry accordingly. Always refer to the manufacturer's installation instructions for the most accurate guidance.
