I decided to go ahead and put on my painted 3v valve covers. Was waiting until the engine came out for the 5.4 swap but since I'm a couple months away from that, I went ahead and did the covers. Not too bad of a swap. Took about 1 hour for each side since it was my first time on the truck.
I used the older style 06 covers that have more bolt holes than the 08's. Fit perfectly. The head still has the bolt holes there to mate up to the older style cover just perfectly.
