After the cylinder head or block have been skimmed. For example. An engine has overheated and the cylinder head has been warped. The head is removed and milled so that the mating surface is flat again. The thickness of the oversized gasket will depend on the amount of material removed. If a thicker gasket wasn't used, the compression ratio may be raised or the pistons may come into contact with the valves
The head, along with everything above it, will have to be removed. If the engine overheated then the head could be warped as well.
When installing the cr 125 head gaskets, make sure to check the surfaces for any old gasket materials or scratches. Check the head to make sure that it isn't warped. Make sure that the cylinder pressure isn't too high. Tighten the head bolts in the proper sequence and at the proper torque, and the gasket should stop blowing.

Bit of a tricky one ... It all depends on the condition of the cylinder head. If the cylinder head is warped then replacing the head gasket won't solve your problem.
