@Klick Design - Thanks for the help.
What do you mean, by "header" (which elements exactly)?
I must tell you that the theme is not designed to function that way and that this is not a support question, but one for custom work.
If you do proceed with this, I suggest you create a child theme and do modification to a child theme (which will save your custom work in the event of updating Cazuela in the future). If you're not sure how this works, you should probably hire a WordPress developer to do this for you (http://jobs.wordpress.net/).
