HKS metal head gaskets are manafactured to resist severe levels of heat that are generated by high-horsepower and high-boost applications. All HKS head gaskets are constructed with multiple layers of steel and coated with a special fluorine rubber to provide exceptional sealing. HKS head gaskets are designed to accommodate standard and certain oversized cylinder bores.
The HKS Stopper-Type gasket is top of the range consisting of the maximum layers of plates possible and utilizes a molded stopper ring around each combustion chamber opening.
