Mastodon Chevy Small Block Valve Cover, Rubber Steel Core Gaskets – Black

Reusable Small Block Chevy valve cover gaskets in molded rubber with steel core — black finish. The rigid steel core gives the gasket the shape retention to handle repeated valve cover removal without tearing or shifting, and the silicone-rubber sealing surface delivers a clean, oil-tight seal even when surfaces aren't perfectly flat.

Sold as a pair (driver + passenger). The gasket of choice when you know the valve covers will come off again — for valve lash adjustments, distributor work, or just routine inspection.
