Ferrea Chevrolet SB 2.055in 5/16in 5.01in 12 Deg Flo Rad Grv +.100 6000 Series Int Valve - Set of 8

These are Ferrea 6000 Series intake valves, specifically made for Chevrolet small-block engines. They feature a 2.055-inch head diameter and a 5/16-inch stem, measuring 5.01 inches overall length. The valves are designed with a 12-degree Flo-Rotor groove and are +.100 inches over standard size, intended for rebuilds where improved airflow and performance are key goals.

Crafted from high-strength steel, these valves are built to withstand the demands of performance engines. The Flo-Rotor groove is a unique design that helps to swirl the air-fuel mixture as it enters the cylinder, promoting more complete combustion and potentially improving power output. The +.100 inch sizing indicates these are intended for engines that have been bored out, requiring a larger valve to match the increased cylinder bore diameter.

This set includes eight valves, enough for a complete set of intake valves for a V8 engine. They are a solid option for anyone rebuilding or upgrading their Chevrolet small-block engine and looking for reliable, well-built internal components.
