New valve covers
I have just received my new valve covers from Rennspeed
http://www.ebay.com/itm/350326839481
Before i fit them should i get them powdercoated/painted or are they okay to be fitted straight on?

You'll have a weap of oil coming from the fixing bolts. The first fix is usually to replace the gaskets, but the covers do warp over time, especially if you've not got exhaust heat shields (like me!)....so then you have to replace with like, or upgrade to billet covers.....

The 92-94 964's had aluminum upper and lower valve covers. The magnesium covers on the earlier cars corrode badly. I think that is the main reason most people replace them. The reason I stayed away from the billet covers was because they don't come with holes to screw the spark plug wire clips to and I've heard that the spark plug holes are too big so the spark plug wire ends don't fit tightly in the hole. These aren't problems with the factory covers. I was able to get factory aluminum covers for $400 for all 4. My $.02.

...advantages?
Standard covers are a (sort of) plastic which eventually warps and then no matter what you do there's a leak.
Billet heads are obviously metal and less prone to warp from the heat of the nearby exhaust!
