I have the tall GMPP valve covers on my 91 and they fit without any issues. I don't have a super ram though, so I can't tell you if that will create issues.

On my 86 I had to cut down the feet on the wiper motor and they fit fine.

If your heads are already center bolt you'll need a set of these to make the perimeter bolt hole covers work:
