Cometic GM Gen-V/VI Big Block V8 .066in MLS Cylinder Head Gasket - 4.320in Bore

When you're rebuilding the top end of your GM Gen-V/VI Big Block V8, you need a head gasket that can handle the pressure. This Multi-Layer Steel (MLS) gasket from Cometic is built to seal effectively, even in high-output engines. It's designed to work with both aluminum and cast iron blocks, and it doesn't require any extra sealants, making installation more straightforward.

What you get here is a well-built gasket made from multiple layers of stainless steel. This construction gives it strength and helps it resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing conditions and different surface finishes. The center layer is stainless steel, and its thickness is varied to meet different requirements, like the .066 inch thickness of this particular gasket. The compressed operating thickness is .036 inches, and the bore size is 4.320 inches.

This gasket fits a range of GM trucks and vans from the early to mid-90s, including models like the Chevrolet C1500 and GMC K2500. It's a solid option for ensuring a good seal between your cylinder head and block.
