Modifying engines for more power than they came with from the factory can sometimes expose weak links in the chain. One of which is often the factory head gasket. Cometic Multi-Layer Metal Headgaskets can hold up to the abuse of racing and enthusiastic recreational driving without failing when put to the test. Please let us know what bore size your engine is when purchasing so we can make sure to get you the right part the first time. Provide maximum sealing performance for today's high output engines and require no sealants Ideal for aluminum heads to aluminum blocks and aluminum heads to cast iron blocks withstanding the shearing force created by the two materials. No need to re-torque, the embossing design of the MLS gasket promotes an even clamp load across the sealing surface allowing for measurable reduced bore distortion Cometic MLS Gaskets are comprized of multiple layers of stainless steel due to it's increased strength, ability to rebound and resistance to corrosion. The outer layers of the gaskets are embossed and coated on both sides with Viton - a flouroelastomer rubber based material that is heat resistant to 250°C /482ºF. 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 layer which can be varied to accommodate multiple thickness requirements.
