You shave the head and the block to remove small defects, such as defects in casting or from wear. The metal head gasket is much less forgiving than an OEM styled one, which is why they require more prep work. Also, have the machine shop that shaves the head/block record how much material they removed. Add that number to the thickness of the compressed OEM gasket, and look for the MHG that's closest to that thickness. This way you are able to maintain the stock compression ratio
