Hooking a bit of code to wp_head

I am looking to hook the code below into the wp_head. I have read the wordpress documentation and understand how to link in single .js files. Just wondered if there was a function i could write in the functions.php to hook the code below in without create a file for it.

<script type="text/javascript">
	Cufon.replace('h1'); // Works without a selector engine
	Cufon.replace('#sub1'); // Requires a selector engine for IE 6-7, see above
</script>

Any help appreciated.
