Cometic Millennium head and base kit for a 3 13/16-inch bore with a .045-inch head gasket and .020-inch base. The MLS-style construction conforms load distribution across the sealing surface and requires less clamp load, helping to limit bore distortion. Installation is simplified because no sealants or re-torque are required, while the layered gasket maintains reliable sealing under varied conditions.
