A multi-layered steel head gasket is a great addition for those of  you increasing the power output to your engine. Multi-layered steel gaskets lower the compression slightly, but can handle the extra pressure produced by a turbocharger. And if you were to put a new head gasket in your vehicle, you can trust Cosworth. Cosworth has earned themselves quite the establishment in motorsports due to their rich racing history. Their head gaskets have been designed to handle the most demanding of conditions. These have been manufactured from pre-coated die cut stainless steel resulting in uniform coating distribution and consistent shape. 

Other feature a 0.25 micron layer of nitrile rubber that provides equal distribution and coverage with no high, or low areas. The die cut manufacturing process ensures smooth edges, and feature a “folded stopper” layer for additional clamping force around each cylinder.
