No you do not.... the valve cover only bolts to the head, and the head bolts to the block... True- these are two different jobs. When changing your valve cover gasket you may just want to ensure that your head bolts and lifters are still torqued down properly. Otherwise, DO NOT remove the head gasket if you simply want to change the valve cover gasket. when replacing the head gasket you should replace the valve cover gasket and may need to (depending on make & model) replace the egr gasket, intake mainifold gasket, and exhaust manifold gasket ...but not the other way around. If your replacing the head gasket ask your local auto shop if they carry a head gasket kit that includes everything necessary in one box...but if your just changing the valve cover gasket then just change that.
