Funny that those are not actually Valve Covers... LoL

I know I'm nit picking, but I was confused when I saw the thread title.

The cam/valve covers are hidden by our air boxes or CAI tubes.

Lastly for these manifolds, I would recommend the silver with black lettering too.

I'll probably be doing that to mine soon, although I'm going to mask a red box around the "6" and leave the 6 Silver.

Good luck... and show pictures when you are done.
