Preheat oven to 350° F (175° C). Grease two 8-1/2x4-1/2-inch loaf pans and line them with a strip of parchment paper, leaving an overhang on both long sides.
In a large bowl, combine flour, baking soda, baking powder nutmeg, cinnamon, cloves, and salt.
In the bowl of a stand mixer or using a large bowl and a hand mixer, combine eggs, white sugar, and brown sugar. Mix on medium-high speed until combined, about 45 seconds. Add in the pumpkin and vegetable oil and mix until combined, about 20 seconds. Add the flour mixture to the bowl and mix until the batter is just blended and smooth.
Divide the batter between the prepared loaf pans.
Bake for about 50–60 minutes, or until the top is nicely browned, and a toothpick inserted into the center comes out clean. Let cool in the pan, about 30 minutes. Then invert onto a cooling rack and let cool completely.
