That's what he doing for the valve retainers, the rest of the cost is
new valves and springs that he had to get from the US plus getting the
valve guides replaced, the valve seats redone then the whole thing
reassembled.

Les is wise but it is *wisdom born of pain* and he's keeping Darren's
pudgy little fingers away from his 4AGE engine.
