FAQ

Q1: Is this cylinder head a “bare” head or does it come with valves and springs?
A1: This is a bare cylinder head. It comes fully machined but does not include valves, springs, seals, or camshaft. You will need to transfer these components from your old head or purchase a new valve train kit separately.

Q2: How can I confirm if this cylinder head fits my engine?
A2: Please locate the casting number on your original cylinder head (usually found on the side or top). Compare it to our part numbers: 8-94431-523-0 or 8-97204376-5. Additionally, measure the length of your cylinder head and the diameter of the head bolts. If unsure, send us a photo of your old head’s casting number for verification.

Q3: What maintenance should I perform when installing a new cylinder head?
A3: Always use a new head gasket and cylinder head bolts (stretch bolts must be replaced). Ensure the engine block deck is clean and flat. Follow the manufacturer’s torque sequence and specification (typically 90-100 Nm for the 4JB1). Also, check valve clearance after installation and adjust if necessary.
