Well, first of all it is less than clear what you want to solve. When
asking for help on a forum like this you should try to formulate a
minimal version of your problem.

It seems you are trying to push C-throughts down the throat of the
lisp interpreter. Lisp has much more flexible lists (and builtin
hashes could be maybe be usefull).

I would heavily recommend a function like

   (defun getheader (header)
     ...
   )  

returns the value of the header "header", or nil if it does not exist.

Well it is all in the manual - but you seem to have started out on a
quite ambitious project. Maybe start with something simpler.
