My original Demon in '71 had them and the engine bay was filthy in less than a month....Michigan weather $uck$. My current Demon will never have them. I thought about glueing the seals on the hood to look like their functional...:dontknow:
I had the same thought for installation of the factory scoops on my 70 Dart. I was thinking that I would glue the scoops to bare metal and paint everything to cover it up.
