FAQ

Q1: How do I confirm this cylinder head will fit my specific Cummins 4BT engine?
A1: The most reliable method is to cross-reference the part number cast or stamped on your original cylinder head with our listed OEM numbers (3933370, 3920005, 3904570). We also recommend matching your engine’s model and serial number to the compatibility list. Our technical team can assist with verification.

Q2: Is this a complete assembly, or does it require additional components?
A2: This is a bare cylinder head casting, machined and ready for installation. It does not include valves, springs, injectors, or other valve train components. You will typically transfer these parts from your old head after inspection or purchase a corresponding valve train rebuild kit.

Q3: What is the recommended procedure after receiving the part to ensure a successful installation?
A3: Before installation, we recommend a visual inspection for any shipping damage. It is also good practice to have a qualified machine shop perform a final surface check and, if necessary, a light deck resurfacing to ensure perfect flatness. Always use a new head gasket and follow the manufacturer’s torque sequence and specifications during assembly.
