Cometic MLS cylinder head gasket for GM LS Gen-3/4 small-block V8 engines with a 4.060-inch bore and 0.070-inch compressed thickness. Embossed stainless steel outer layers coated with Viton create a durable seal without additional sealants. The uncoated center shim allows thickness tuning; MLS construction evens load distribution, withstands aluminum-to-aluminum or aluminum-to-iron shearing, lowers clamp load needs and helps limit bore distortion. Viton coating resists heat to 250°C (482°F).
