Cylinder Head Machining – Professional Resurfacing

Machine the face of your cylinder head

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. When we machine or surface the head, the valves may come closer to the face and potentially collide with the pistons. If the valve depth is not within specification, we may be unable to machine the face without reseating the valves and performing a complete service.

  • Precision machining – restores flat sealing surface.
  • Professional service – experienced technicians
  • Perth workshop – pickup available in Midland

From $176.00 AUD
