68 383 valve covers differences

Is there any difference in 68 BB mopar valve cover between body styles or std vs HP? Any other years the same as 68? I know the cover from 69 up but not sure on my 68 parts. I need to verify some 68 HP covers. Thanks

A valve cover for a 68 RR will have a bracket on the pass side for the heater hoses.

I think that is std but the wire looms is what I’m not sure of.
