that means that they should really only go on the index_body.html, viewforum_body.html and viewtopic_body.html files.
having said that, open those files in a good text editor and paste you google code at the top or bottom of those pages.
using ftp, download the relevant files, open them in a text editor only, paste your code, save the file and upload back,
then, go in your admin panel and purge the cache and then refresh your browser.
