Troubles Changing the Header on Vantage Theme

Hello, I am having troubles figuring out how to allow different Headers for different pages. I have successfully added a header image (by selecting “them settings” and then adding it in “logo image”) as well as have put a phone number in the “header text” area. Everything looks great, but the problem is that I don’t want this same header display on EVERY single one of my pages. Is there a better method to create headers on this theme? OR is there perhaps a simple way to change the header on other pages (ex: via a plugin or option perhaps)?
