It's not head gaskets. Replace the valve cover gaskets.

Most probable cause is the head gasket has worn out allowing oil to seep through to the plugs. If you don't want to replace it go to a parts store and get a good gasket sealer additive for the oil and hope for the best after about 200-500 miles. Otherwise the likely solution is to replace the head gasket.
