Cometic's MLS head gasket for GM LS Gen-3/4 small block V8s comes in a 4.190" bore with .092" compressed thickness. The multi-layer stainless construction combines embossed outer layers with an uncoated center shim to vary thickness and clamp load. The gasket design promotes even load distribution across the sealing face and reduces bore distortion while delivering durable combustion sealing.
