Monkey,
Soak the heads in some water. Then double bag the heads making each bag totally sealed. Put in a heated area and "sweat them" off. Could take a week or so. Be careful opening the bags afterwards do it out side it will smell!!!!!!!
If your making euros be careful boiling. In my opinion boiling is the very last option. Beetles much better and maceration is better than boiling. if your doing a euro make sure you degrease and if you want it white whiten it. This will give you a great trophy for ever.
