As far as "wear pattern indentations", none. As far as "wear patterns", I saw more there than was mentioned.
There is a Lunati cam which Summit sells as their cam in a white box which is pretty close to the OEM 383HP cam for a good price. A few threads in here where people have used it for a replacement on a 10.0CR 383 4bbl 1968 cam. A little bit more duration and lift, but n0t much. That might be a good option.
