Cometic 2006+ GM LS7 7.0L 4.150 inch Bore .086 inch MLS-5 Head Gasket

Starting with a .086 inch compressed thickness, this Cometic Multi-Layer Steel (MLS) head gasket is built for the demands of high-output engines like the GM LS7 7.0L. It's designed to provide maximum sealing performance without needing any additional sealants, making installation more straightforward. These gaskets are well-suited for applications using aluminum heads with either aluminum or cast iron blocks, as the multiple stainless steel layers can handle the shearing forces that arise from dissimilar materials. The increased strength from these layers also allows the gasket to rebound and resist corrosion, ensuring a solid seal over time.

The outer layers of this gasket are embossed and coated on both sides with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit. This Viton coating is engineered to perform reliably in harsh sealing environments and under various load conditions. The center layer is uncoated stainless steel, and its thickness can be varied to meet different sealing requirements, which is how Cometic achieves the specific .086 inch overall thickness for this gasket. This construction helps ensure consistent performance and durability for your engine.
