What is a Cylinder Head? A cylinder head is usually located on the top of the engine block. It serves as a housing for components such as the intake and exhaust valves, springs and lifters and the combustion chamber. This page covers the main function and various designs of cylinder heads, and their causes and symptoms of failure.
Cylinder heads are an important part of a combustion engine. A cylinder head in an OHV engine generally contains valve train components, such as pushrods, poppet valves and other components that are operated by a camshaft located in the cylinder block. By contrast, OHC engines have the camshaft itself in the head,...
In an internal combustion engine, the cylinder head (often informally abbreviated to just head) sits above the cylinders on top of the cylinder block. It closes in the top of the cylinder, forming the combustion chamber. This joint is sealed by a head gasket. In most engines, the head also provides space for the passages that feed air and fuel to the cylinder, and that allow the exhaust to escape.
Driving your vehicle with a properly functioning cylinder head is critical. A warped or worn head can lead to decreased power, poor fuel economy, overheating and potential engine failure.

The internal combustion engine inside of a vehicle has cylinders in it. The top of these cylinders contains what are called cylinder heads. There are pistons which close these cylinder heads so that air and fuel can be compressed inside of the combustion chamber.
The cylinder head is located at the top of the engine block. Made from aluminum or iron, it seals the piston chambers, ensuring adequate pressure within them. The first engines using this technology, comparable with the modern engines used to power automobiles today, were patented in the early 1860s.
Cylinder Heads. Bolt on a set of fully assembled heads for instant power gains or custom build your engine’s top-end around a set of bare castings! Plus, you can turn up the horsepower even more by choosing heads with CNC-ported runners and chambers, CNC-profiled chambers, raised exhaust runners, and other enhancements.
Remanufactured Cylinder Heads. A remanufactured cylinder head is a head that has been rebuilt with parts that are still serviceable. Some cylinder heads have been welded or repaired. All cylinder heads are pressure tested to assure a leak-free casting. New valve seats have been installed when needed.
Engine configuration is an engineering term for the layout of the major components of a reciprocating piston internal combustion engine. These components are the cylinders and crankshafts in particular but also, sometimes, the camshaft(s). Many apparently 'standard' names for configurations are historic, arbitrary, or overlapping. For example, the 180° V engine is so named because the crankshaft is related to a V engine more closely than it is related to other opposed-piston engines such as the boxer. Others would consider it a flat engine because of its shape. The names W engine and rotary engine have each been used for several unconnected designs. The H-4 and H-6 engines produced by Subaru are not H engines at all, but boxer engines. The Subaru H-4 and H-6 designs are so named because they are horizontally opposed pistons.
Jaguar XK engine in a Jaguar E-Type Jaguar XK engine in a 1955 Jaguar D-Type XK150 4.2-litre XK in a Jaguar 420 The Jaguar XK6 is an inline 6-cylinder dual overhead camshaft (DOHC) engine produced by Jaguar Cars between 1949 and 1992. Introduced as a 3.4-litre, it earned fame on both the road and track, being was produced in five displacements between 2.4 and 4.2-litres for Jaguar passenger cars, with other sizes being made by Jaguar and privateers for racing.
Four-stroke cycle (or Otto cycle) A cylinder is the central working part of a reciprocating engine or pump, the space in which a piston travels. Multiple cylinders are commonly arranged side by side in a bank, or engine block, which is typically cast from aluminum or cast iron before receiving precision machine work. Cylinders may be sleeved (lined with a harder metal) or sleeveless (with a wear-resistant coating such as Nikasil). A sleeveless engine may also be referred to as a "parent-bore engine". A cylinder's displacement, or swept volume, can be calculated by multiplying its cross-sectional area (the square of half the bore by pi) by the distance the piston travels within the cylinder (the stroke). The engine displacement can be calculated by multiplying the swept volume of one cylinder by the number of cylinders. Presented symbolically, A piston is seated inside each cylinder by several metal piston rings fitted around its outside surface in machined grooves; typically two for compressional sealing and one to seal the oil.
