Hi neo!
I'd just understood a bit more

I can change the $header with the logo insert code without the links buttons on each templates where I don't want the buttons appears to.
Now the question is:
Can I make more than one variable for $header?
Example:
$header means logo and buttons.
$header1 means just logo.
If it's possible to do it, what's the code to write in the new variable and where must I put that code?
Thanks.
