The Cometic MLS cylinder head gasket for Porsche 47-series and M31 engines is built from embossed stainless layers with Viton-coated outer faces and an adjustable stainless shim, sized for an 88mm bore and roughly 0.098" thickness. It provides sealant-free sealing for high-output applications, resists shear and corrosion between dissimilar materials, and helps distribute clamp load to protect bore geometry.
