Cylinder Head Machining – Professional Resurfacing
Expert cylinder head resurfacing in our Perth workshop. Precision machining to restore your cylinder head’s sealing surface — essential for proper head gasket sealing and engine performance. Please note that the valves must be set to a specific depth below the cylinder head face. When we machine or surface the head, the valves move closer to the face and may hit the pistons. If the valve depth is not within specification, we may be unable to machine the face without reseating the valves.
From $243.00 AUD Call us to discuss your cylinder head machining needs.
