i'm almost 100% that mopar never put chrome valve covers on any motor from the factory. maybe someone knows better...
but i think they should be engine color (engines were painted as whole assemblies)
67 GTXs and 67 R/Ts had chrome valve covers from the factory. If i remember correctly they did not show up again on a factory car (truck) until 1978 on the Little Reds.
Hey 696pack, were they standard or optional as an engine dress up package?
I have seen them numerous times and knew that they were originals.
