Cylinder Heads & Parts

What Are Cylinder Heads and Why Are They Important?

Your vehicle’s engine is a precision-tuned machine with thousands of parts working together to keep you on the road. One critical engine component is the cylinder head, which often includes various smaller components, such as valves, valve springs, pushrods, and more. These components work to control the air-fuel mixture needed for the combustion process that powers your vehicle.

The cylinder head plays a crucial role in maintaining the compression your engine needs for optimal performance. When paired with the cylinder head gasket, , it seals the top of each cylinder, ensuring efficient compression. If the gasket fails or the cylinder head becomes cracked or warped, compression is lost—resulting in poor engine performance or even total engine failure.
