Hello Ron,
I disagree about gluing the gasket to the head. When adjusting the cam shims, which requires removing the cam, that gasket will get torn and you'll be replacing it. Also, those D rubbers should be flush with the gasket surface of the head. If they are not, they may have shrunk from age, and perhaps new are in order. I glue all my valve cover gaskets to the valve cover, using silicone type sealant. Then on the surface to the head use hylomar which remains soft such that you can remove the cover and the gasket is unhurt. I do use silicone around the cam seal though, but be sparing with it since I've been warned that lose silicone in the motor isn't a good thing, and when removing the cover for a cam check, it will release fairly easily. As for the washers on the hold down bolts, I just use what Bean and other sell, they seem to work fine but keep a new set on hand as they seem to work only once. The cork gasket seems more compliant than the fiber one they now sell so if you can find one, get it as long as it isn't too old since the cork seems to shrink if it isn't restrained.
I wish you well.....
