The cylinder heads play an important role when it comes to maintaining your engine's performance. They're made of either aluminum or cast iron, and sit on top of the engine block where they protect the various engine parts in three ways.

What Cylinder Heads Do

The cylinder head draws air and fuel into the engine to feed combustion, and is also responsible for dispelling the exhaust gases. Secondly, cylinder heads help to direct coolant throughout the engine, where it cools the many parts so they can run at peak performance. Finally, a cylinder head teams with the gasket to prevent coolant and oil from getting into the combustion chamber.
