Cylinder head resurfacing is just one of the jobs that is usually required when rebuilding an engine or reconditioning a cylinder head. It is an extremely important job because the surface finish that is put on the head (and engine block) affects not only the head gasket’s ability to cold seal fluids and combustion gases, but also its long term durability.

Surface condition
Another condition that can affect sealing is scratches. Every scratch is a potential leak path along which fluids and pressure can migrate. If a scratch is deep enough, coolant may find its way into the crankcase or cylinders before the engine is fired up. Or, combustion gases may force their way past the gasket into the cooling jacket or an adjacent cylinder, eventually causing the gasket to burn out and fail. If scratches, pitting or erosion are present on the head and/or block, resurfacing is required to remove the flaws.
