Actually, I was wrong! It is only the headers that are in the #+BEGIN_SRC line 
that get stripped.  The contents of any #+header: lines are left  alone and the 
src-block transcoder will have access to them as the :header element of a plist 
in the src-block argument.

I think this might work: Add `after' advice to `org-babel-exp-code' that copies 
the header args you want to retain and prepends a #+header: line with them to 
the string returned by org-babel-exp-code.  Then your src-block transcoder can 
find them.
