Product Details

Starting with a 1.88-inch diameter, this individual exhaust valve from Edelbrock is built from hardened tip stainless steel. This material choice helps it stand up to the heat and stress of the exhaust cycle, while the hardened tip adds durability where it counts. The valve features an undercut stem design, which is a smart way to improve airflow past the valve head. This means your engine can breathe a little easier, potentially leading to better performance.

This valve is a 1-piece construction, meaning the stem and head are forged as a single unit, which is generally a strong design. It's also swirl-polished, a finishing process that smooths the surface to reduce friction and further aid airflow. The overall length is 5.450 inches, and it's designed to fit specific Edelbrock cylinder heads like the #60459, #60479, #60499, #60559, and #60439. It's also suitable for Chevrolet Big-Block Mark IV engines from 396 to 502 cubic inches.
