1.6L/1.4L 16v Vauxhall Cometic Metal Head Gasket 1.7mm
1.4L/1.6L 16v Cometic head gaskets will suit bore sizes up to 82mm, thickness 1.7mm
These gaskets are designed for high stress applications and in our tests so far, are impervious to problems experienced when using pump fuels in high compression engine and in our opinion no other gasket comes close to the Cometic gasket. The 1.7mm gaskets is a five-layer gasket; this gasket has been designed specifically to allow you to give a cylinder head that has been skimmed excessively due to damage, extended life. You must remember through when using this thicker head gasket that your squish (this is the distance between the head of the piston & the head face) is being reduced. This is not good for performance & should only be done as a last resort, until you can afford a new cylinder head.
The only other time we would use this head gasket would be to allow you to run high compression pistons without machining the crown, this will give you the opportunity to use the high compression pistons on a lower specification kit, which you will then be able to upgrade later without having to replace the pistons again.
Not suitable for 8v engines.
Also available in 1.3mm thickness, GSK16-1.3MM-82.
