Cometic Chevrolet 4.3L Gen-1 90 Degree V6 .120in MLS Cylinder Head Gasket - 4.060in Bore

What you get here is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chevrolet 4.3L Gen-1 90-degree V6 engines with a 4.060 inch bore. This gasket is built to handle the demands of higher output engines, offering a compressed thickness of .120 inches. It's a well-built component that doesn't require any additional sealants, making installation more straightforward.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This makes it suitable for use with both aluminum and cast iron blocks, and it's designed to withstand the shearing forces that can occur between different metals. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, ensuring a precise fit for your engine build.

This gasket is a solid option for a wide range of Chevrolet and GMC vehicles from the mid-80s through the mid-90s, including models like the Chevrolet Astro, GMC C1500, and Chevrolet S10. It's a key part for anyone rebuilding the top end of their engine.
