Cosworth High Performance multi-layer steel head gaskets are designed to seal in power under the most demanding conditions. Each gasket is carefully engineered.

Specification
Individual die cut layer of stainless steel with superior consistency compared to laser cut gaskets
Pre-coated stainless steel using nitrile rubber that is exactly 0.25 microns thick
Manufacturing dimensional tolerance of .00001”
Die cut manufacturing process ensures smooth edges, unlike laser cut gaskets
Cosworth head gaskets are manufacture from pre-coated material ensuring consistent distribution of coating with no high or low spots
Coswoth gaskets feature a “stopper” layer for additional torque around each cylinder
The width of sealing area is specific for each application thereby providing ultimate sealing properties
Every Cosworth high performance head gasket has been engineered to ensure absolute perfect distribution of torque around each cylinder. Gaskets that do no include the feature may have torque “spikes” around each head bolt along with torque “valleys” between the cylinder bolts resulting in uneven and or poor sealing
