Cylinder heads

Upon receiving or removal of your cylinder head they are fully stripped and placed in our metalas de greaser. The cylinder head is then pressure tested to ensure it is serviceable.

All parts are cleaned and inspected inc:

Valve guides, valves, valve springs and replaced where necessary.   

The cylinder head is then de-coked and machined to ensure a flat uniformed surface, valve seats re-cut.

Valves are decoked and re-cut, The cylinder head is then reassembled with new valve stem oil seals.

The valves are then vac tested to ensure a gas tight seal.

Please see repairs and fitting for our fitting service.
