Cometic GM 6.5L Diesel 4.100 inch Bore .086 inch (91-95)Find parts that fit my vehicle

Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.086". Right Side. Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.

Whether its for a full rebuild or some standard maintenance, the proper engine components are needed to make sure your vehicle is running smooth.

Head Gaskets sit between the engine block and cylinder head. They prevent the mixture of any gasses and oils with the cooling system of your car. If the head gasket goes bad on your vehicle, it could cause extreme amounts of damage. If you're going to increase the amount of horsepower in your car, we recommend making sure your head gasket is in good condition.
