When it comes to high performance head gaskets, HKS Metal Head Gaskets are the perfect way to seal your Scion FRS cylinder head. Made from multilayer steel gasket material, that is coated in a flourine based rubber to seal under even the harshest conditions. Resistance to all automotive chemicals, heat, and combustion pressure makes HKS Head Gaskets the perfect choice for any performance engine rebuild. Available in multiple thicknesses for some applications, you can match the gasket thickness to suit your performance needs. HKS Metal gaskets come in either bead or stopper design. Stopper is designed to handle higher combustion pressures, and is what we offer for most kits. The Bead seal design is primarily for low boost or NA motors and are labeled as Bead Style Gaskets.
Note: Compression ratio estimates are based on stock internals, deck height, and cylinder head; and may vary based on your specific combination of parts.
