Cylinder Head Reconditioning Process



On arrival we allocate a job number & after removal from the block we disassemble, chemically clean & inspect checking valves & valve guides, retainer & collets condition & test valve spring pressures.


The cylinder head body is checked for height, straightness & hardness & pressure tested in a submersible pressure tester checking for any cracks or porous leaks & check all threads.


After inspection we prepare a report & quotation as part of the engine reconditioning process & advise you of the cost to recondition your engine which usually can save you hundreds of dollars compared to outright replacement.
