Maximum Sealing for High-Output GM LS Engines

When building a high-performance GM LS1 engine, the integrity of your cylinder head seal is paramount. The Cometic GM LS1 3.910 inch Bore .040 inch MLS Head Gasket is engineered to provide a superior seal that withstands the extreme pressures and temperatures of modern performance builds. By utilizing a multi-layer stainless steel (MLS) design, this gasket offers exceptional strength, rebound, and corrosion resistance.

Advanced MLS Technology

The gasket features outer layers embossed and coated on both sides with Viton, a high-temperature fluoroelastomer rubber. This specialized coating is heat resistant up to 250°C (482°F), ensuring a reliable seal even under harsh operating conditions. Whether you are running aluminum heads on an aluminum block or a mixed-material setup, this gasket is designed to handle the shearing forces created by thermal expansion.
