This all results in superior surface contact between block and cylinder head.All head Gasket layers\/spacers go through an additional process to significantly reduce forming induced stress. Advantages are reduced brittleness in material, increased Flexibility and deformation retention.This stabilizes the Gasket, resulting in reduced cylinder bore distortion and improved combustion seal fro the extreme cylinder pressures found in high compression, supercharged and turbocharged applications. A proprietary polymer coating ensures the micro-seal of engine coolant and oil fluids.\u003cbr\u003e\u003cbr\u003eA typical MLS head Gasket requires a smoother (30Ra) surface finish than composite head Gaskets.Mr. Gasket's proprietary polymer coating will seal a surface finish twice as rough (60Ra) as a typical MLS head Gasket.
