For the record: I did not port or machine or do anything to these heads. All work was done by Jakob Spring from Danmark. I mentioned his website before iirc.

My best guess however is that he used a rolled sandpaper bit in a drill or dremel to finalize smoothing of the port, which also gave it that structure.
