while my motor was being built by Josh at JS Performance...i had always envisioned car color-matching metallic blue valve covers on the engine...i dont know the place Josh sent them to but they did an awesome job (ended up with quite a few pieces coated..my super ram lid and vortech elbow going to the supercharger)
you can kinda see it in my avatar but if you want clear pics you can see at Josh's site..
