Cometic Chevrolet Gen-1 Small Block V8 .098in MLS Cylinder Head Gasket - 4.200in Bore

Cometic Gasket is well-known for making solid sealing solutions, and their Multi-Layer Steel (MLS) head gaskets are a popular choice for high-output engines. This particular gasket, part number C5403-098, is designed for Chevrolet Gen-1 Small Block V8 engines and features a 4.200-inch bore. It's built to handle the demands of modern performance applications.

This MLS gasket is constructed from multiple layers of stainless steel, giving it increased strength and the ability to rebound and resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well in tough sealing environments. The center layer is uncoated stainless steel, allowing for different thickness options; this gasket has a compressed operating thickness of 0.036 inches. 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 popular models like the Chevrolet Camaro, GMC C1500, and Buick Regal from the early to mid-1980s. It's important to note that this gasket is intended for aftermarket heads and features undersized water ports, which allows for custom fitting during installation.
