Correct.  The former is only for export, and doesn=E2=80=99t work with babel
features (incl. tangling)

Something like (untested):

,----
| #+begin_src emacs-lisp
|   (org-babel-goto-named-src-block "preamble")
|   (org-babel-tangle)
| #+end_src
|=20
| #+name: preamble
| #+begin_src latex :tangle preamble.tex
|   % code goes here
| #+end_src
`----

You=E2=80=99ll need to use some combination of =E2=80=9C:exports none=E2=80=
=9D or a headline
tagged :noexport: to avoid these src blocks showing up in the exported
output.

HTH,
