You don't keep the old studs so just take them off with vice grips. If they are turning hard you will need to smack them on the end with a hammer to loosen them up, you do not want to break one. Nooow, I don't use the shoulderless studs that come with the rubber gasket. Many people have had problems with the nut hitting the bald spot before the valve cover is tightened down. The G60 valve cover the rubber valve cover gasket was used on is thicker. I get allen head set screws fully threaded, no bald spot and use blue lock tite to set them in.
