I customized my own header and want it to be inserted between the second and the third line of the document. Unfortunately I'm not very used to Lisp, therefore I have a hard time trying to find the corresponding lines in header2.el. Any ideas on how to proceed?

As the Commentary of header2.el says:

;; To have Emacs update file headers automatically whenever you save a
;; file, put this in your init file (~/.emacs):
;;
;;   (autoload 'auto-update-file-header "header2")
;;   (add-hook 'write-file-hooks 'auto-update-file-header)
;;
;; To have Emacs add a file header whenever you create a new file in
;; some mode, put this in your init file (~/.emacs):
;;
;;   (autoload 'auto-make-header "header2")
;;   (add-hook 'emacs-lisp-mode-hook 'auto-make-header)
;;   (add-hook 'c-mode-common-hook   'auto-make-header)

If you want the header to contain two lines of your choice as its first two lines then just define a function that inserts those two lines, and put that function at the beginning of option make-header-hook. E.g.:

(defun insert-my-first-two-lines ()
  (insert "MY FIRST LINE")
  (insert "MY SECOND LINE"))

M-x customize-option make-header-hook

Click INS in Customize at the beginning of the default value of make-header-hook, to insert insert-my-first-two-lines:

INS DEL insert-my-first-two-lines

Save your customization.

Automatic updating of the header, by update-file-header, will do nothing to those first two lines (which I guess is what you want). It changes only lines for which you have defined an updating action using register-file-header-action.
