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.
 
For use with PRB, PNC, and PPA cylinder heads so it has more water passages,(picture is not accurate) but fits all K20 Variants.

Specifications:

• Individual die cut layers of stainless steel with superior consistency compared to lasercut 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
