header material too close to staff

[David Zelinsky]

Is there a way to put some space between the header material and the
first staff?  None of my searching as produced anything relevant.

Here's an example:

-------------

\version "2.20.0"
\include "english.ly"

\score {
  {
    c''' c''' c''' c'''
  }
}
\header {
  piece = "blah blah blah blah blah blah"
}
