Cometic Chevy Gen-1 Small Block V8 .070in MLS Cylinder Head Gasket - 4.165in Bore

When you're rebuilding the top end of your Chevy Gen-1 Small Block V8, a good head gasket is crucial for sealing the combustion chamber and coolant passages. This Cometic Multi-Layer Steel (MLS) gasket is designed for engines with a 4.165-inch bore and a 0.070-inch compressed thickness, fitting a wide range of vehicles from the early 80s, including models like the Chevrolet Camaro and GMC C1500.

Cometic's MLS gaskets are built with multiple layers of stainless steel, which gives them strength and the ability to rebound, helping them resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes without needing additional sealants. The center layer is stainless steel, allowing for different thickness options to meet specific engine build needs.

This gasket is a solid option for both aluminum and cast iron blocks, and it's designed to handle the shearing forces that can occur when mating different metals. The valve-pocketed bore and steam holes are also noted features for this specific gasket design.
