Cometic GM LS Gen-3/4 Small Block V8 .070in MLS Cylinder Head Gasket - 3.910in Bore

If you're rebuilding the top end of your GM LS Gen-3/4 small block V8, getting the right head gasket is crucial for a solid seal. This Cometic Multi-Layer Steel (MLS) gasket is built to handle the demands of high-output engines, ensuring a reliable seal between your cylinder head and block.

Cometic uses multiple layers of stainless steel for 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, making it suitable for both aluminum-to-aluminum and aluminum-to-cast iron setups. The center layer is stainless steel and can be varied to achieve different thicknesses; this particular gasket has a compressed thickness of .070 inches with a 3.910-inch bore, designed to fit a wide range of GM LS engines found in vehicles like the Chevrolet Silverado, GMC Sierra, and Cadillac CTS.

These MLS gaskets are designed to provide maximum sealing performance without needing additional sealants, simplifying the installation process. They are well-suited for applications where the engine is pushed harder than stock, offering a durable and dependable seal.
