Hello Bill,
We can change the color of the powdercoat on everything, we will need to strip the powdercoat off and redo them all to get it all to match. When you send down the pieces I can get them over to the powdercoat stripper and see what the cost will be for you. As for removing the valve cover, it is pretty straight forward. Just unplug the coils, unplug the 2 actuators at the front, remove the breather line and then loosen all of the bolts holding it in place and it will come off. You can send me an email at Dave@ddmworks.com also and we will get you taken care of. Thanks!
