Features & Product Details

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.

Subaru gaskets are sold individually. Order two for a complete set.
  • Bore = 101mm, Thickness = 1.5mm
  • 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.

  • This gasket is suitable for lowering the compression ratio when using EJ20 heads on an EJ25 short block.

    PRICE IS PER GASKET! 2 are required for a motor build.
