So, cylinder heads are usually located on the top of the engine block. Usually, called the top end. It serves as a housing for components; such as the intake and exhaust valves; springs and lifters and the combustion chamber.
Also, The passages in the head allow air and fuel to flow inside the cylinder. While, permitting the exhaust gases to flow out of it. The passages are otherwise called ports or tracts. The head also channels the coolant into the engine block. Consequently, cooling down the engine components. The cylinder head uses a gasket that aids in preventing; water or oil from leaking; into the combustion chambers.
Most (OEM) heads are made out of cast iron. As a result, a head made of cast iron is more durable and less expensive. However, cast-iron is heavy and provides a lesser efficiency in dissipating heat. For this reason, some manufacturers prefer using heads made of aluminum. But, are also prone to head gasket leaks. These heads are much lighter than cast-iron cylinder heads. Performance cars and race cars; commonly have aluminum cylinder heads.
So, cars with inline (straight) engines have one head. Automobiles with V engines have two heads. One for each bank. Finally, this makes replacing a head much more affordable.
