Cometic Chevy Small Block 4.125 inch Bore .030 inch MLS Head Gasket (w/All Steam Holes)

Cometic Gasket is a well-known name for creating reliable sealing solutions, especially for high-output engines. This Multi-Layer Steel (MLS) head gasket is built for Chevy Small Block V8 engines and is designed to handle the demands of performance builds. It features a 4.125-inch bore and a compressed thickness of .030 inches, making it suitable for specific engine configurations.

The construction of this gasket uses 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 tough sealing environments and various surface finishes. This design means the gasket doesn't require any additional sealants, and it's effective when mating aluminum heads to either aluminum or cast iron blocks, as it can manage the shearing forces between different metals. The center layer is stainless steel, allowing for variations in thickness to meet specific engine needs.

This gasket fits a wide range of vehicles, including models like the Chevrolet Camaro, GMC C1500, and Buick Century from the early to mid-1980s. It's a solid option if you're rebuilding or working on the top end of your Gen-1 Small Block Chevy.
