Edelbrock 8- Chev E-Tec 170 Exh Valves 1 550 X 4 930

If you're working on a Small-Block Gen I Chevrolet engine, specifically the 262 through 400 cubic inch displacements, these Edelbrock E-Tec 170 exhaust valves are a solid choice. They are designed to fit Edelbrock's #60797 cylinder heads, and they're built from a single piece of hardened tip stainless steel. This material choice helps them stand up to the heat and stress of the exhaust side of combustion.

What really sets these valves apart is the swirl-polished finish on the face and the undercut stems. The swirl polishing helps reduce carbon buildup, keeping the valve sealing better for longer. The undercut stems are a smart design feature that actually increases the airflow around the valve when it's open, which can lead to a noticeable improvement in engine performance. They measure 1.55 inches in diameter and have an overall length of 4.930 inches, with hard-chromed stems that are 11/32 inches.

This set includes eight exhaust valves, which is exactly what you'll need for a V8 engine. They're a well-built component that can make a difference in how your engine breathes.
