Cometic head and base kit for a 3-9/16-inch bore with a .051-inch head gasket and .020-inch base. The MLS-style gasket conforms load distribution across the sealing area and requires less clamp load, which helps prevent bore distortion. No sealants or re-torque are necessary, providing a reliable sealing solution for engines where tight control of bore geometry is important.
