About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring an outer coating of Viton rubber. This construction is designed to handle the demands of high-output engines, providing a reliable seal between aluminum heads and blocks, or aluminum heads and cast iron blocks, without needing additional sealants. The Viton coating is heat resistant up to 482 degrees Fahrenheit, making it suitable for harsh sealing environments and varied surface finishes.

The center layer of this gasket is uncoated stainless steel, allowing for precise thickness control. In this case, the compressed operating thickness is set at 0.066 inches, with a bore size of 4.150 inches, specifically suited for GM LS7 7.0L engines. The multi-layer stainless steel design offers increased strength and resilience, helping to resist corrosion and maintain sealing performance under stress.
