I would seriously consider replacing the valve seals while it is out. You can do it with a spark plug adapter to apply air to the cylinder and a pry bar tool to compress the springs. Very cheap repair and at that age with low miles I can tell you the valve seals will be hard and cracked and can cause a big oil loss and smoke. Just a suggestion.
Thanks. Good advice and it would be easy while the engine was out. I remember when I was young(er) we had a '76 Winnebago Brave with the same affliction with its 440. Valve guide seals led to smoking and oil loss.
