yea forgot that your ganna wanna drain the oil do your tear down and id pour a quart or 2 of cheap oil through to rinse out any coolant

Some opt to do the valve cover gaskest since they already have it taken down that far

Clean all parts and gasket surfaces very well I used a couple engine cleaning brushes on a drill and synthetic steel wool pads along with a gasket scraper

And superglue is reat to have handy incase you break a vacuum line trust me
