FAQ

Q: Is this cylinder head a bare casting or a complete assembly?
A: This is a complete core assembly. It includes the cast iron head with pre-installed valve guides, valve seats, and core plugs. However, it does not include valves, springs, retainers, or the camshaft. You will need to transfer these components from your old head or order them separately.

Q: Will this head fit my 1991 Ford F-250 with a 4BT engine?
A: Yes, this head is a direct OEM replacement for the 4BT engine used in Ford trucks of that era. We recommend confirming your existing part number (3933370, 3920005, or 3904570) to guarantee compatibility. If your head has a different number, please contact us for cross-referencing.

Q: What maintenance steps are required before installation?
A: Before installation, we recommend cleaning the head gasket surface on the engine block, applying new head bolts (torque to spec), and using a high-quality diesel engine oil. Ensure the cylinder head is free from any debris. It is also advisable to check valve clearance after installation for optimal performance.
