How To Insert Facebook Conversion Pixel To Header Tag

Anyone have idea how to insert this code in header tag?

by my reading it can be done using CClientScript




<!-- Facebook Conversion Code for cashout -->

<script type="text/javascript">

var fb_param = {};

fb_param.pixel_id = 'XXXX';

fb_param.value = '0.00';

fb_param.currency = 'MYR';

(function(){

  var fpw = document.createElement('script');

  fpw.async = true;

  fpw.src = '//connect.facebook.net/en_US/fp.js';

  var ref = document.getElementsByTagName('script')[0];

  ref.parentNode.insertBefore(fpw, ref);

})();

</script>

<noscript><img height="1" width="1" alt="" style="display:none" src="facebook.com/offsite_event.php?id=XXXX&amp;value=0&amp;currency=MYR" /></noscript>



Thanks in advance
