Preheat oven to 350 degrees F. Grease and flour two 9x5 inch loaf pans.
In a medium bowl, whisk together the flour, baking soda, salt, cinnamon, nutmeg, cloves, ginger, pumpkin spice. Set aside.
In a large mixing bowl, mix together pumpkin puree, eggs, oil, butter, water, sugars and vanilla until well blended.
Gradually add the dry ingredients into the pumpkin mixture until just blended. Pour into the prepared pans.
Fold in walnuts with a wooden spoon or spatula.
Bake in preheated oven 45-50 minutes or until toothpick inserted into the center comes out clean.
While the pumpkin bread is cooling, combine all of the ingredients for the spiced glaze.
Drizzle over bread and allow the glaze to dry before serving.
