I don't think anything gets stripped out but it may also depend on how the heads are attached to the tripod. I have the 3221 which has a removeable center column. It has a metal top where you can screw your head to and it's got three set screws to keep the head in place. There's also a screw base (not sure what it's really called) at the bottom of the column which is comes off and it made of heavy plastic. When you take the center column off, you can place this plastic base on the tripod and attach a different head on it. So, my Wimberly is screwed onto the center column proper and the 486RC2 head is screwed on to the plastic screw base. When the tripod is set on its legs with the Wimberly head on top, the 486RC2 is hanging upside down at the bottom of the center column.
If you don't have a center column that works like mine does, it might be a pain to be screwing off one head and screwing on another though.
Interesting, I will be doing all this on a Gitzo 1327
