Cometic Chevrolet Gen-1 Small Block V8 .030in MLS Cylinder Head Gasket - 4.135in Bore

Cometic Gasket is well-known for making reliable sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example of their work for performance engines. This particular gasket is designed for Chevrolet Gen-1 Small Block V8 engines and features a 4.135-inch bore, with a compressed operating thickness of 0.030 inches. It's a solid option for those rebuilding or upgrading their top end, especially when using aftermarket heads, as it includes undersized water ports that allow for custom fitting to your specific setup.

What makes these MLS gaskets stand out is their construction. They're built from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping them resist corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit and is designed to seal well in tough conditions. The center layer is uncoated stainless steel, and its thickness can be varied to achieve different compressed thicknesses, like the 0.030 inches on this gasket. These gaskets are suitable for use with both aluminum and cast iron blocks and heads, and they don't require any additional sealants.

This gasket fits a wide range of vehicles, including many Chevrolet and GMC trucks and cars from the early to mid-1980s, as well as models like the Avanti II and Checker Marathon. If you're working on a performance build or a restoration that demands a dependable seal, this Cometic gasket is a well-built choice.
