The Cometic MLS cylinder head gasket for Porsche 47-series and M31 engines is sized for an 88mm bore with an approximate 0.066" compressed thickness. Its embossed stainless outer layers are coated with Viton and the stainless shim layer allows thickness customization. The MLS design seals aluminum-to-aluminum or aluminum-to-iron interfaces without sealants and reduces clamp load to limit bore distortion.
