Ferrea Chevrolet SB 1.6in 7mm 5.38in 0.29in +.400 Super Alloy Exh Valve - Single (Drop Ship Only)

This Ferrea exhaust valve is made from a super alloy, a material chosen for its ability to withstand the high temperatures and stresses found in the exhaust port of a Chevrolet Small Block engine. It measures 1.6 inches in diameter and has a 7mm stem, with an overall length of 5.38 inches. This particular valve is +.400 inch over size, meaning it's designed to replace a stock valve that has been machined to accept a larger diameter, often done during an engine rebuild to improve flow or compensate for wear.

The super alloy construction offers improved heat resistance and durability compared to standard materials, which is crucial for exhaust valves that operate in the hottest part of the combustion cycle. The 7mm stem is a common size for many performance and stock applications, and the specific dimensions are important for ensuring proper fitment within the valve guide and sealing against the valve seat. This valve is sold individually, so you'll need to order the correct quantity for your engine.
