The head closes the cylinder from above and contains the combustion chamber, the valves and the spark plug; cylinder filling depends on it.
It should be replaced if it is cracked, the valve seats are burnt, compression is lost, or the surface is warped from overheating. Fit new gaskets at the same time and check the valves and springs. Not sure whether the part will fit? Call the store and we will help you choose for your model.
