I don't know if anybody's already addressed this issue, but I discovered this, today. I noticed a discolored, worn 3/8" diameter spot in the top front of the aluminum valve cover. It's coming from inside the hood center front mounting screw for the fake louvers. I laid a paper envelope on the top of the engine and shut the hood. That screw head made a dent right through the envelope. I took the screw out, repeatedly, grinding more and more off of the head, until it wouldn't grab the T-25 torques driver. I screwed it in as much as I could with a small pair of channel-locks. Tested it with the envelope again and it was still making a small dent in it.
