Cometic Millennium head and base kit for a 3 13/16-inch bore with a .030-inch head gasket and .020-inch base. The MLS-style construction conforms load distribution across the sealing area and requires less clamp load to reduce bore distortion. No sealants or re-torque are required, offering a durable sealing solution for engines where maintaining bore geometry is important.
