PDI Big Boss Cylinder Heads

What is a cylinder head?

---

The cylinder head is an essential piece of the engine that houses the fuel injectors, exhaust valves, and intake valves. It contains the combustion chamber and provides structural support and ensures that the chamber is sealed and fully enclosed.
Having a damaged cylinder gasket puts the entire engine at risk, and while they are made to last the life of the engine, there are times where the cylinder head needs to be replaced. If you are looking for cylinder head replacement for your heavy-duty diesel engine, then a PDI cylinder head may be the option you are looking for.
