if you use gooble (gasket sealer) around water ports or oil for that matter theres a chance of a bit getting in the water ports later on down the road and cause over heating problems. no matter how little you put on if there was ever a leaker later on the rtv can be pushed into the motor. ON that note i wouldnt put rtv around any ports. gaskets are made to be put on dry. thats the whole purpose of gaskets. Back in the day did they have to use it? no and today there gaskets are coming out better and better as years go on. Not to mention you can cause a air pocket and it will start its own leak. better off just getting your hands a little dirty put some elbow grease in it and do with out it. may take a little longer to line up correctly but now your sure your not gonna clog up your motor and as long as you torque the bolts to book foot lbs you shouldnt leak. trust me do it right or have it done by a profetional so its warrented!!
