I am not sure what about the exact layout you are trying to achieve. 
Does this give you what you want.


\setuppapersize[letter]
\setuppagenumbering
   [alternative=doublesided,location=]
\setuplayout
        [backspace=1.0in,
        topspace=0.5in,
        width=4.5in,
        height=9.5in,
        rightmargin=2.35in,
        rightmargindistance=0.15in,
        leftmargin=0in,
        leftmargindistance=0in,
        header=\normallineheight,
        headerdistance=\dimexpr0.5in-\normallineheight,
        footer=0in]

\setupheadertexts[chapter][pagenumber][pagenumber][chapter]
\setupbackgrounds[header][text][bottomframe=on,rulethickness=1pt]


  \starttext
  \chapter{Test}
  This is a test of some math stuff. $0 = g_{\mu\nu}dx^\nu dx^\nu$.
  \dorecurse{10}{\input knuth}

  \showlayout
  \stoptext
