Grease and flour a 9x5x3 inch loaf pan. Preheat the oven to 350 F.
In a large bowl sift together the flour, baking soda, salt, nutmeg, cardamom, cinnamon, allspice, and cloves. Stir in sugar. In a small bowl beat together eggs, pumpkin, oil, and vanilla. Pour wet ingredients into dry ingredients and stir until just combined. Be careful not to over mix batter
Immediately pour batter into prepared pan. If desired, sprinkle top of loaf with a 1/2 cup of salted roasted pumpkin seeds. Bake in preheated oven for 45 to 50 minutes, or until a knife inserted into the center of the loaf comes out clean. Cool, in the pan, on a wire rack for 5 minutes. Turn out bread onto cooling rack and let cool to room temperature.
