Delete Header

I would like to delete my header. I want to nest my blog into my existing frames website. I want to use my existing website header instead of the the WP header.

I figured out how to remove the text, but I have not been able to remove the space. When nested in frames the blog starts too low on the screen and I would like it to start just below the frames header.

Any suggestions? I have not found info in the online docs yet to support what I am looking to do.

THANKS IN ADVANCE.
