The Cometic MLS cylinder head gasket for Porsche 47-series and M31 engines features embossed stainless outer layers coated with Viton and a configurable uncoated stainless shim, sized for an 88mm bore and about 0.140" thickness. The multi-layer design seals mixed head and block materials without sealants, resists corrosion and shear, and helps distribute load to reduce bore distortion in demanding engines.
