Cometic Chevrolet 4.3L Gen-1 90 Degree V6 .075in MLS Cylinder Head Gasket - 4.155in Bore

When you're rebuilding the top end of your Chevrolet 4.3L Gen-1 90-degree V6, a solid cylinder head gasket is crucial for a good seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of higher output engines. It features multiple layers of stainless steel for strength and rebound resistance, helping to prevent leaks and maintain compression.

The outer layers of this gasket are embossed and coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes. This construction means you don't need additional sealants, and it's designed to work well with both aluminum and cast iron blocks. The center layer is stainless steel, and its thickness is varied to meet different requirements – in this case, it's set at 0.075 inches with a 4.155-inch bore to match your specific engine.

This gasket fits a wide range of Chevrolet and GMC trucks and SUVs from the mid-80s to the mid-90s, including popular models like the Chevrolet Astro, S10, and GMC C1500. It's a well-built component designed for reliable sealing in your engine build.
