Looking for some info on installing rocker cover gaskets so they dont leak.I have not yet used the new rocker cover gaskets because I am still setting this motor up so it runs properly-timing and valve adjustment.How  is anyone installing these gaskets?Are you using sealer on both the cover and the head?What are you using as sealer-silicone?If I need to remove later to readjust valves do I automatically need new gaskets?I put the covers back on with the old gaskets but they are dripping a little because of the volume of oil now going to the valves.l
