Use the following setup for the header, it use natural tables.

\startsetups pagehead

\bTABLE[option=stretch,strut=no,offset=.5em]
  \bTR
    \bTD[align={right,lohi},width=4cm] left \eTD
    \bTD[align={middle,lohi},width=6cm] middle \eTD
    \bTD[align={left,lohi},width=4cm] right \eTD
  \eTR
\eTABLE

\stopsetups
