GTGRAVELYPARTS has contracted with an American manufacturer of industrial gaskets to produce the gaskets L-series owners need most often at excellent prices. Our gaskets are made using a modern materials and techniques, and are the exact same size, shape, and thickness of Factory originals.
  Our Head, Intake, and Exhaust Gaskets are made of a superior material that, unlike the originals, will NOT warp, corrode, rot, rust, or deteriorate. In fact, this new material actually conforms to the imperfections found in the head and cylinder, thereby sealing them, when properly installed and torqued, providing the cylinder or head are not warped too much.
  If you have any questions, please do not hesitate to contact us.
