Ferrea Chevrolet SB 1.65in 5/16in 5.01in Inconel +.1 S-Alloy Exh Valve - Single (Drop Ship Only)

Ferrea is well-known for making high-performance valvetrain components, and this Inconel exhaust valve is a prime example of their work for Chevrolet SB engines. This single exhaust valve measures 1.65 inches in diameter and features a 5/16 inch stem with an overall length of 5.01 inches. It's designed as a +.100 inch oversized valve, meaning it's intended to replace a stock valve that has been machined to accept a larger diameter for improved airflow.

The valve is constructed from Inconel, a superalloy known for its exceptional strength and resistance to extreme heat and corrosion. This makes it a solid choice for demanding engine builds where high exhaust gas temperatures are common. The S-Alloy designation indicates a specific material composition optimized for durability under stress.
