Rep Power: 296 Are you looking for recommendations to someone who does it or just asking how it is done? Just ask around, getting stuff chromed isn't cheap either, i would go with the polished aluminum.

Rep Power: 296 You would have to go somewhere that deals with chroming, hard to say who would do it for you, you could send it away and have it coated?

Rep Power: 251 chrome looks good. but if its your daily driver you may run into some problems. a chrome plated peice does not dissapate heat very well, meaning that the valve cover will become significantly hotter than it would otherwise. obviously this causes excess stress and wear on the parts.

Rep Power: 372 I had a polished valve cover on my 94 civic ex that I polished my self. I bought a used valve cover from the junk yard and I went to town on it myself.
If you are using the one that is on the engine, make sure you remove it from the car first, it can get really messy while you are sanding it.
I first cleaned the valve cover with a strong degreaser to get any grease off that was on the ouside and inside of the cover
Start sanding, use 240 grit until you don't see ANY dark little dots in the finish, just lots of scratches.
Go to 400 grit, start sanding. Sand until the first rough scratches are TOTALLY gone and new, finer scratches are left. At this point, you may see some little dots (dimples in the cast). If there are a lot it will mar the finish, just like bubbles in paint, so go back to those spots with 240 again and then 400 until you're satisfied that they're gone.
Now sand with 800 grit. Keep in mind, what ever surface flaws (like deep visible scratches) that are there after you're done with this will still be there when you're done, so be thorough.
Now use a wool pad or a tool that you can buff the valve cover to a bright shine. I used Mothers Aluminum polish, and I used my regular car polisher, and then I used my Dremel with a polishing pad on the end. It took a little longer but I was able to get into the nooks and the crannys.
It came out awesome - and was well worth the small investment of sandpaper and aluminum polish
