A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression Gaskets allow for “less-than-perfect” mating surfaces on machine parts where they can fill irregularities. Gaskets are commonly produced by cutting from sheet materials.
Gaskets for specific applications, such as high pressure steam systems, may contain asbestos. However, due to health hazards associated with asbestos exposure, non-asbestos gasket materials are used when practical.
It is usually desirable that the gasket be made from a material that is to some degree yielding such that it is able to deform and tightly fill the space it is designed for, including any slight irregularities. A few gaskets require an application of sealant directly to the gasket surface to function properly.
Spears Racing head gaskets is compressed between the engine block and the cylinder head. The head gasket seals in the internal combustion process and also keeps coolant and oil from mixing together as the two fluids travel from the engine block to the cylinder head. Head gaskets themselves are not very expensive
This gasket is custom made to Spears Racing Specifications it will increase your Compression from Stock . The thickness is made thinner than original gasket to get more powerful results for Torque and RWHP .This gasket is used by competitors in all of the major race series.
Spears Racing’s High compression head gaskets are comprised of one layer of Stainless Steel not two like the OEM gasket. Spears Racing uses Stainless steel for increased strength, its ability to rebound and corrosion resistance. The layer of the gasket are embossed and coated on both sides and are designed to meet the demands of a variety of harsh sealing environments, load conditions and surface finishes. Heat resistant to 250C or 482F
