You can drop the \definebodyfontenvironment line when you use 
\definefont to set the part fonts, e.g.

\definefont[PartText][SerifBold sa 5]
\setuphead[part][textstyle=PartText]

You shouldn't use it because Hans kept it only for backwards 
compatibility and \defineheadplacement is the better alternative. You 
can also use the same rendering (the content of the setups environment) 
for different head alternatives where you set the differences with the 
\defineheadalternative command.

% HeadA

\defineheadplacement[HeadA][vertical]#1#2%
   {\startframedtext
      #1\quad #2%
    \stopframedtext}

\definehead[HeadA][section][alternative=HeadA]

% HeadB

\defineheadalternative[HeadB][renderingsetup=HeadB] % alternative=vertical

\startsetups[HeadB]
   \startframedtext
     \headnumbercontent \qquad \headtextcontent
   \stopframedtext
\stopsetups

\definehead[HeadB][section][alternative=HeadB]

\starttext

\HeadA{Knuth}

\input knuth

\HeadB{Tufte}

\input tufte

\stoptext
