Filter to grab wp_head contents

Hey,

I’ve looked through the docs extensively—Action Reference, Filter Reference—even gone through some of the source files like general-template.php and default-filters.php to try and find a hook that allows me to grab and manipulate (for purposes of cache busting within my plugin) the contents of the wp_head function. More specifically, the output of the functions wp_print_styles, and wp_print_head_scripts.

If anyone could help me with a link to an appropriate and existing filter, or suggest where I can go in order to get access to this particular part of the page rendering (without modifying the core, of course) it would be greatly appreciated.

Cheers.
