Standard Copper
The standard copper gasket is suitable for the majority of road going engines and is suitable for bore sizes up to +0.020".

Composite Gasket
For race engines, or those with a larger bore size, we supply composite gaskets. As standard these will cope with a bore size up to 84mm (the equivalent to +0.055").
We can also supply a 'big bore' version of this head gasket which is large enough for a bore size of 88mm (the largest forged pistons we supply are 87mm).
