Question

Quizplus · Accepted Answer

Technician A is correct because cylinder head resurfacing machines do include grinders and milling machines, which are used to ensure the surface is flat and can properly seal with the engine block and gasket. Technician B is incorrect because cylinder head reconditioning often starts with inspection and cleaning, followed by resurfacing of the cylinder head itself, not necessarily starting with the valves.
