Cylinder heads need to be robust. They have to withstand huge pressures and very high temperatures, while retaining their shape and form to seal the cylinder block via the head gasket. They’re key to controlling air flow in and out of the cylinders and fuel deployment.

The cylinder head also holds the injectors and valves – and contains more moving parts than any other part of the engine.

Although largely unnoticed, the cylinder head plays a key role in your engine. It’s a solid item that sits at the top of your unit and covers its workings. It’s sealed in place with the head gasket.

The inside of the cylinder head contains a number of passages – known as ports or tracks – and the air mix travels along these to the inlet valves. Other tracks inside the cylinder head are the route by which the exhaust gases travel when leaving the main engine block.



Types of diesel engine cylinder head cover     

Automotive 4-Stroke Engine Head Designs - Valve and Camshaft Configurations

Common Names


Intake Valves

Exhaust Valves


Double Overhead Cam




Allows optimum positioning of the valves for crossflow cylinder head.
Double camshafts are used to allow direct actuation of well-placed valves, without rockers.
Widespread in modern car design

Overhead Cam




Widely used for cars in recent decades, but increasingly superseded by DOHC.

Overhead Valve
OHV, I-Head, Pushrod




Still used in big V8 pushrod engines
Needs pushrods and rockers to actuate valves

Flathead, L-Head, T-Head




Once universal, now obsolete
Simplest possible configuration
Cams operate directly on the valves

IOE, F-Head




Always uncommon, obsolete for decades
