The ceramic coating spray cans you can get at any decent autoparts store, kragen, autozone, napa, etc. I got my header used from ebay, and this is what I did: Cleaned it, remove any oil and rust on it then sand it with medium grit sand paper. You might need higher grit since I would recomend you remove the black paint before spraying them with ceramic. Install them and let the car warm up to operating temp. THEN spray them while ON the car. This way the paint wont bubble. You could also spray them lightly while off the car, and brush or sand of the chips once it bubbles. The ceramic coating is silver btw. As for the valve cover, do a quick search on it, there are many threads and maybe even some walkthroughs. Ill get pics of it tonight, and have them on here tomorrow.
