Preheat oven to 350 degrees F (175 degrees C). Grease 12 muffin cups or line with paper muffin liners.
In a bowl, add whole wheat flour, sugar, salt, baking soda, baking powder, walnuts, cinnamon, cloves, nutmeg and allspice.
In a separate bowl, beat together pumpkin puree, vegetable oil and eggs.
Add and stir pumpkin mixture into flour mixture until smooth. Scoop batter into prepared muffin cups.
Bake in preheated oven for approximately 25 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
