Motor coming out of six for a re-seal. while it is out I want to trim the turbo valve cover fins. Anyone have a picture or pattern of where to trim?? Searched, no find

Here's a photo I found for you. On my cars, we simply shaved down all the ribs a bit, but this photo shows which need trimming.Click to view attachment

I had all the fins shaved down about 5/16th
