Jeff, it's a good game plan to give it an Italian tune first. Burn the carbon off the valve seats and valves. If you adjust it with carbon on the valve seating area the valve will never close and you'll burn out a valve.

I take the covers off, rotate the engine as per the instructions and feel each valve's subtle click. In 25 years of doing my own SC's valves I've only had to adjust half a dozen. They really don't wear out or get out of adjustment much. If the valve doesn't have the subtle click, adjust it then. But there is no point in unscrewing the lot of them and resetting them.

If someone's engine needs a whole lot adjusted I think there is something badly wrong with the engine and that needs to be addressed first.
