\inrightmargin takes care of a 'unbiased' placement in the right margin,
which saves you some hard coded values,  

\def\myhead#1#2%
  {\setbox0=\ruledhbox{#1}%
   \setbox2=\ruledhbox{#2}%
   \setbox0=\hbox{\lower\ht0\hbox{\raise\ht2\box0}}%
   \ht0=\ht2 \dp0=0pt
   \hbox{\box2\inrightmargin{\box0}}}

The lower and raise commands make sure that the number hangs, and the ht/dp
assignment obscures the number, 
of course you need to remove the 'ruled' after you see what happens.
