Cylinder Heads

Cylinder Heads

The cylinder head is one of the most critical components in any diesel or gas engine. It houses the combustion chambers, valves, injectors, and often the camshaft — playing a direct role in airflow, compression, and fuel injection. Any failure in the cylinder head can lead to major engine inefficiency, loss of power, or complete breakdown.

At AMS Parts, we supply high-quality new, OEM, and remanufactured cylinder heads for a wide range of industrial, generator, and marine engines — supporting everything from routine overhauls to emergency replacements.

When Should Cylinder Heads Be Replaced or Reconditioned?

• At recommended service intervals as part of a top-end overhaul
• If cracked, warped, or damaged due to overheating or coolant failure
• When valve seats are worn or combustion leakage occurs
• During rebuilds after extended high-load or high-hour usage
• If injectors or valve guides are no longer seating properly
