Cylinder Heads

1.Exchange Cylinder Heads

Our exchange cylinder heads are remanufactured to exacting tolerances using the most up to date equipment in Australia and are remanufactured to Australian standards. All our exchange cylinder heads are pressure tested, digitally hardness tested, and checked for thickness prior to being chemically cleaned and blasted.

All cylinder head dimensions are then checked, repaired where necessary and machined to exacting tolerances, some as small .001 of a millimetre. We make extensive use of diamond & carbide tooling and specialist measuring equipment to ensure our exchange cylinder heads are the best in the industry.

Combine our superior product with our no deposit policy and 12 months unlimited km warranty, you are assured your getting the best.

2.New Cylinder Heads

We carry a range of brand new cylinder heads for many popular makes and models, both petrol and diesel. These cylinder heads are supplied complete with valves, springs and rocker gear where applicable.

We also carry a large range of gasket sets and head bolt sets to support our exchange and new cylinder head range.

3.One-Off Cylinder Heads

For those occasions when a new or exchange cylinder head is not available, or your cylinder head is a vintage, performance, industrial or racing cylinder head, we offer a one-off reconditioning service using the same high-tech equipment and exact standards as our exchange range.

Our cylinder head machining capabilities include:

  • Diamond facing of cylinder heads up to 1.5m in length
  • Precision machining of valve seats from 4mm guide diameter up to 12mm guide diameter and 3.5" seat diameter.
  • Repair or replacement of any size valve guides
  • Cylinder head pressure testing with hot and cold hydraulic testing capabilities
  • Hardness testing of aluminium heads (Click Here for more information on the Softness of Aluminium Heads)
  • Machining for screw in studs
  • Cylinder head welding and repairs (including broken bolt and thread repairs)
  • Valve facing

We offer a complete reconditioning and restoration service for classic and vintage cylinder heads. As in the case with this MGB 1800 cylinder head, we can upgrade heads, designed to run on leaded fuel, to run on unleaded fuel.

The valve guides were badly worn and there was heavy carbon build-up and recessed valve seats caused from running on unleaded fuel.

New valves and guides were fitted, along with valve seats to suit unleaded fuel and the face was machined.


The damage caused from dropping a valve can be quite extensive.  These CHI Cleveland heads are well worth repairing.  The finished product is below.

Frequently Asked Questions

How do I know if my engine needs reconditioning?

Tell-tale signs that your engine requires attention are that it has lost performance or efficiency, it blows excessive smoke or it has developed an unusual noise.  However, a vehicle needn't have these symptoms to benefit from a reconditoned engine.  A complete and comprehensive recondition of your engine will increase power, fuel efficiency and extend the life of your vehicle.

Can I supply my own parts?

Yes. You are quite welcome to supply your own new parts should you have a preference for a particular brand name.  However, our parts prices are very competitive and our high standards ensure that only quality parts are fitted to any job.  We have liaisons with many Australian and international companies allowing us to have access to world-wide sourcing of parts.

Do you offer engines which suit LPG?

As LPG has different properties to unleaded fuel, an engine can experience problems when converted to LPG.  We can offer options which can enhance the performance and reliability of an LPG engine.  Galloway Engine Reconditioning also stock a range of exchange heads which are modified to run on LPG.
