The heads should all go back on and stay fairly snug. I don't really want to lose the articulation if possible. I know some of the Forarm parts are a little difficult to keep together. The funny thing is, that I developeed a better technique for attaching the extened forarm to a rolled up sleeve after I made these. Use glue if you have to to keep them together. I did not want to comitt them to a specific pose because I did not know how you wanted to display them in the Dio.
