It is 3mm thick.
Ideal for use with cranks with 110mm long conrods or to get your squish clearance/port timings right.
There is a large variation in casing height (the distance between an imaginary line running through the middle of your crankshaft and the base gasket surface) especially on Indian casings so this gasket may help you get round that.
It includes extra area to allow for big welded up race type transfer ports.
