Box Headers

I have a couple boxes that I would like to remove the header lines from is it possible to pick and choose which ones you want headers on and which you do not?  Or is it an all or none deal.  Specifically some of the html blocks I am adding I would like no header bar on.  Thanks in advance for anyones help.

.. any box at different pages obey by admin builders as you know. All these blocks used headers.

You can just try to remove this headers from blocks as you wish. Or change header
