Add to Cart:

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.

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
