Cometic twin-cam head-and-base gasket kit for a 3.938-inch bore with a .045-inch head gasket and an O-ring base. The MLS-style construction conforms load distribution across the sealing surface and requires less clamp load, helping minimize bore distortion. No sealants or re-torque are needed, offering straightforward installation and consistent sealing for high-duty twin-cam engines.
