Cometic Chevrolet 4.3L Gen-1 90 Degree V6 .060in MLS Cylinder Head Gasket - 4.155in Bore

Cometic Gasket is well-known for making reliable engine components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s built for Chevrolet 4.3L Gen-1 90-degree V6 engines, specifically designed for a 4.155-inch bore and a compressed thickness of 0.060 inches. This gasket is a solid option for rebuilding or repairing a wide range of vehicles, including models like the Chevrolet Astro, C1500, and S10, as well as GMC C1500 and G1500 trucks.

What makes this gasket stand out is its construction. It uses multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This Viton coating ensures a strong seal even under demanding conditions and works well with both aluminum and cast iron blocks, preventing the shearing forces that can occur between different metals. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.060 inches found in this specific gasket.

Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward. This design is ideal for high-output engines where a reliable seal is critical.
