Cometic GM LS Gen-3/4 Small Block V8 .027in MLS Cylinder Head Gasket-Bore 4.125in

Cometic Gasket has a reputation for making well-built engine components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s designed for GM LS Gen-3 and Gen-4 small block V8 engines, fitting a wide range of vehicles like the Chevrolet Camaro, Corvette, and Pontiac GTO. This gasket is crucial for sealing the combustion chamber, ensuring proper compression and preventing coolant or oil leaks between the cylinder head and the engine block.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well in harsh sealing environments. The center layer is stainless steel and can be varied in thickness to meet different requirements; in this case, it’s set to a compressed operating thickness of 0.098 inches with a bore size of 4.125 inches, making it suitable for engines with Darton MID sleeves. Because it's an MLS gasket, it doesn't require any sealants and is effective with both aluminum and cast iron blocks.
