I don't have any but seems to me that would come in handy in particular situations, such as: intake manifold, exhaust manifold, bell housing bolts/nuts, and starter bolts.
Frankly, I don't miss: distributors, caps, points, rotors, condensers, carburetors, plug wires, adjusting valves or generators! My newer Volkswagen (2002 New Beetle Turbo S: 1.8T) is to the point were all you have to do is change plugs, filters, clean mafs and throttle bodies! Aside from specific replacement intervals on timing belts, water pumps, tensioners and serpentine belts this thing doesn't require much in the way of "tuneups" at all!
