The Cometic MLS cylinder head gasket for AMC 4.0L inline-6 is a multi-layer stainless steel gasket that seals demanding engines without sealants. Embossed outer layers coated with Viton and AMP sit above an uncoated shim layer that can be varied to set thickness and rebound. Offered in .027 in nominal thickness with a 3.950 in bore, it reduces clamp load, minimizes bore distortion, and evens load across the sealing area.
