Being they are graphite gaskets dont use any sealer just clean surface with brake clean dont go sanding.Also the clean valves in the first cyl is that from cleaning or did it come off that way? Being that clean thats possible where the water leak was. Is there a chamber on both sides that clean?
Not sure what you are referencing in the pics. All the valves are identical in person. Here is what they used to look like.
