About this part

Product Details

These are Ferrea 6000 Series exhaust valves, designed for Chevrolet Small Block 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 20-degree back angle and a relieved margin for improved flow, and they are +.150 inches longer than stock to accommodate certain cylinder head modifications.

Ferrea uses high-quality materials for their valves, and the 6000 Series is known for its durability and performance. The valves are constructed from a strong, heat-resistant alloy that can handle the demands of performance engines. The relieved margin design helps reduce turbulence and improve the flow of exhaust gases out of the cylinder, which can contribute to better overall engine performance. The extended length is useful when working with aftermarket cylinder heads that may have different port heights or require specific valve train geometry.
