New Style Gm Vlv Cvr Gsk

The New Style GM Vlv Cvr Gsk by Mr. Gasket is a purpose-built valve cover gasket engineered for Small Block Chevy engines, delivering reliable sealing and durability where it matters most. Whether you're rebuilding a classic muscle car, maintaining a modern performance build, or restoring a street engine, this gasket prevents oil seepage and contamination at the cylinder head interface. Mechanics and enthusiasts trust this design because it combines traditional materials with proven engineering to handle both stock and modified engine configurations.

This gasket features a rubber-coated cork core construction at 0.187 inches thick, a time-tested material combination that resists oil degradation and maintains a consistent seal across a wide temperature range. The center bolt design provides secure, even clamping force across the entire gasket face, minimizing hot spots and edge lifting under sustained engine operation. The rubber coating protects the cork substrate from direct contact with hot oil, extending gasket life and reducing the risk of premature failure that can plague cheaper alternatives. This dual-layer approach is particularly effective in street and performance applications where temperature cycling and vibration are constant stressors.

Sold as a pair, this gasket set covers both valve covers on Small Block Chevy platforms, including 305, 350, and 400 cubic inch engines commonly found in Chevrolet trucks, Camaros, Corvettes, and performance builds. Installation is straightforward—simply clean the valve cover and cylinder head mating surfaces, position the gasket, and torque the cover bolts in a crisscross pattern to spec. Mechanics prefer Mr. Gasket's products for their consistency and availability, making replacement and sourcing hassle-free for both professional shops and DIY builders.
