Hello Pablo,\setupheads doesn't work for this - see the test:----\setupheads[distance=1in]\setuphead[subsection][distance=2in]\starttext \section{Sec} \subsection{Subsec}\stoptext----Subsection has the specified distance of 1 in, whilst the section doesn't.Section was altered by \setupheads, whilst subsection by \setuphead.Wiki http://wiki.contextgarden.net/Command/setupheads says that \setuphead has some more options than \setupheads.
The \setupheads command is only a synonym for \setuphead but there can be a difference between
\setuphead[..,..=..,..]
and
\setuphead[<section][..,..=..,..]
