The JE Pro Seal left-side head gasket for Ford Modular 4.6/5.4 2V/4V engines fits a 3.63 inch bore and uses a 0.039 inch thickness to match factory left-bank dimensions. It is a direct-fit replacement for left-bank cylinder head service during modular engine rebuilds or repairs, helping restore correct head-to-block sealing and compression when bore and thickness specifications are followed.
