I thought the MP black wrinkle covers would fit. But whoever here said they would hit the manifolds they sure did. I couldn't even install them. The chrome ones should definitely seal better than these original 30+ valve covers I would think. The passenger side one is leaking right on top of the manifold, you can see it come from the valve cover edge. It smokes too bad and it may cause a fire. I was wondering if I get a quality chrome valve cover like MP or Edelbrock would they have any fit problems. I would love some NOS 73+ valve covers but I don't know if there are anymore. I'd like to at least try and stay with some plain chrome or with the Mopar logo so it still looks stock or stock appearing.
