My bag of tricks:
Dremel flap sander in the 'pockets' for the bolts. Narrow brush for the grooves on the top. Wide brush for the pocket bottoms (around the bolt hole in the corners). Air tools for roughing in (one pass each tool), then 120 and 240 grit on the Ryobi sander, then two grits of scotch-brite pads.
Total time invested is about 30-35 minutes each valve cover to go from both looking like the left:
Just one pass with each tool/grit.
