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';


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

  fpw.async = true;

  fpw.src = '//';

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

  ref.parentNode.insertBefore(fpw, ref);



<noscript><img height="1" width="1" alt="" style="display:none" src=";value=0&amp;currency=MYR" /></noscript>

Thanks in advance
