Clean around where the valve cover goes. Make sure it is dry. Then apply the RTV Sealant where it shows below. The back should look like the front even though it's hard to see the back in this picture. Basically start half way down from the top of the "hump" on the head, and seal down to the first bolt hole. Do this on EACH corner. Put the new valve cover gasket on the valve cover (and remove the old gasket if needed.) Put the valve cover on and hand start each bolt.
