Cometic MLS cylinder head gasket for GM LS Gen-3/4 small-block V8 engines with a 4.060-inch bore and 0.030-inch compressed thickness. Multiple embossed stainless steel layers with Viton-coated outer faces offer robust sealing without auxiliary sealants. An uncoated center shim permits thickness tuning; MLS design distributes clamp load evenly, copes with dissimilar-material shearing, lowers required clamp load and reduces bore distortion.
