Cometic Chevrolet 4.3L Gen-1 90 Degree V6 .060in MLS Cylinder Head Gasket - 4.060in Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed operating thickness of 0.060 inches and a 4.060-inch bore, specifically designed for Chevrolet 4.3L Gen-1 90-degree V6 engines. MLS gaskets are constructed from multiple layers of stainless steel, offering increased strength and resistance to corrosion, making them ideal for high-output applications. They can handle the shearing forces between aluminum and cast iron blocks, and between aluminum heads and blocks, without needing additional sealants.

The outer layers of this gasket are embossed and coated with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit (250 C). This coating is designed to perform in harsh sealing environments and under various load conditions. The center layer is uncoated stainless steel, allowing for precise thickness control to meet specific engine requirements. This well-built gasket fits a range of vehicles, including Chevrolet Astro, C1500, and GMC C2500 models.
