About Cosworth High Performance Head Gaskets

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 multilayer 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.

Folded stopper layer provides complete sealing around entire combustion chamber	Without folded stopper layer, clamping force is limited resulting in incomplete sealing around combustion chamber

Each gasket is carefully engineered with the following features:

• 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 clamping force 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
