I'm excited to announce that thejdm is now updated to the latest phpbb 3.2 software. You may notice the site is now mobile friendly but with the upgrade comes some hiccups. theGarage, theGallery, theArcade are no longer supported. In due time the developers should be working to release the modifications to work on the new software. #LetsMakeForumsGreatAgain

As far as actually PORTING the head, if you don't know what you're doing you can do more harm than good. A little polish never hurt anybody though, just going through the passages knocking down the casting burrs and imperfections with a sanding disc. I did this to a D16 head in high school and won a blue ribbon at the tech ed expo.
