The ultimate "power tool" for polishing....a lapidary polisher:

The photo above is sort of misleading, the belts stick out well beyond the "cowl" of the polisher and access for flat items is pretty decent.
"Polishing belts" are available from 60 grit (Those take a LOT of material off VERY quickly) to around 1200 grit (useful for polishing).
The wide belt is stable and you can hold the valve covers securelywith both hands...only light pressure is needed. Most rock polishers use a wet-belt system to keep the polishing belts from getting clogged with "dust", debris, whatever you want to call it.
You can do a set of valve covers in about 10 minutes....15 seconds each with a 100 grit, 30 seconds with a 220 grit, 45 seconds with a 600 grit, then it's just a matter of polishing to your heart's content with 800 and 1200 grits.
If you want a mirror polish, get a polishing pad for a shop grinder and use either jeweler's rouge (good) or cerium oxide (best--will leave a glass-like finish)! I use that system on custom glass "bottleneck slides" that guitar players use, can make about 20 of them an hour after the necks are cut off the wine bottles.
