Ido a bunch evey year. Skin the head, remove the lower jaw, I use an outside type propane burner and big pot, boil the head for about 2 1/2 to 3 hours in water with a couple or three squirts of dish soap, remove the head and pressure wash it clean, blow all the brain matter and nasal matter out with the pressure washer, dump water and replace with clean water and a big bottle of peroxide, boil head in that for another 30 minutes, let dry, preferably in the sun. Thats it. I get placks for them from here.
