OK -- the nuts on my '87 are captive. I was preparing for the worst, when I discovered that they were captive, to my great joy.
My meaning was that I would replace all other gaskets. Te valve cover gasket is the only one I'd plan on re-using. Now I've re-used other gasket due emergency situations (such as lack of proper planning), but I don't plan it that way.
