HKS metal head gaskets are uniquely engineered to prevent severe levels of heat that are generated by high-horsepower and high-boost applications. All HKS head gaskets are made with multiple layers of steel and coated with a special fluorine rubber to give exceptional sealing. HKS head gaskets are designed to accommodate standard and certain oversized cylinder bores. For most applications, multiple gasket thicknesses are available to change the dynamic compression ratio for various levels of tuning and engine conditions. (Note: HKS gaskets are not designed to cure sealing problems caused by head or block irregularities.) The HKS Bead-Type gasket features a raised bead structure around each combustion chamber to ensure a precise seal. A bead is a type of spring used to maintain surface pressure which is very well suited to head gasket use. The beads are laid out to provide optimum pressure and seal around the combustion chamber. By carefully designing and adjusting the bead shape and heights, precise control of surface pressure is achieved for optimum results. Using a combination of 3 different types of beads allows maximum efficiency and performance.
