Cosworth Performance Racing Head Gasket

Cosworth Head Gasket

Cosworth High Performance Head Gaskets are engineered to seal in power under the most demanding conditions. Constructed from stainless steel with a folded stopper layer, each application features superior sealing compared to conventional multi layer steel gaskets. Additionally, Cosworth High Performance Head Gaskets are manufactured from pre-coated die cut stainless steel resulting in uniform coating distribution and consistent shape.

Cosworth Performance Head Gaskets Feature:
  • Individual die cut layers of stainless steel with superior consistency compared to laser cut gaskets
  • Pre-coated stainless steel with a 0.25 micron layer of nitrile rubber ensures consistent distribution of coating with no high or low areas
  • Manufacturing dimensional tolerance of +/- 0.001”
  • Die cut manufacturing process ensures smooth edges, unlike laser cut gaskets
  • Cosworth gaskets feature a “folded stopper” layer for additional torque around each cylinder. The width of sealing area is specific for each application thereby providing ultimate sealing properties
  • Available in a range of thicknesses for specific applications
