Mix the sour cream, two cups of shredded cheese, green onions, cream cheese, chopped ham, green chilies and Worcestershire sauce in a large mixing bowl. Beat until everything is evenly combined.
Slice the top third off the bread. Set aside. Using a spoon or clean hands, carve out the interior of the loaf of bread, leaving a one-inch border. Reserve the bread you spooned out for dipping.
Spread the dip into the hollowed-out bread. Top the dip with the remaining shredded cheddar cheese. Wrap the bread bowl completely in foil.
Bake for one hour.
Serve as a dip with the hollowed-out bread, crackers or chips.
