Cometic Chevrolet 4.3L Gen-1 90 Degree V6 .051in MLS Cylinder Head Gasket - 4.060in Bore

If you're rebuilding the top end of your Chevrolet 4.3L Gen-1 V6, a good head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these engines, offering a solid seal that won't break down over time.

Cometic uses multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures and various sealing environments. This construction means the gasket requires no additional sealants, making installation more straightforward. The compressed thickness is 0.051 inches with a 4.060-inch bore, designed to fit a range of Chevrolet and GMC vehicles from the mid-80s to the mid-90s, including popular models like the S10, C1500, and Astro vans.
