Unfortunately, this grabs only an approximate space, and the exact
amount
depends on the usual "badness" of a normal break. One way to ensure
getting the right space is to eliminate the badness of ordinary breaks:
\topskip 1\topskip plus1000\p@ \r@ggedbottomtrue % like \raggedbottom;
moreso
\def\need#1{\vskip #1\penalty \z@ \vskip-#1}
Which works pretty well, if you don't mind raggedbottom pages.
Finally, there is another method that works very well, as long as you
use it between paragraphs: (I.e., not in a \vadjust{}.)
\def\need#1{\par \penalty-100 \begingroup % preserve \dimen@
\dimen@\pagegoal \advance\dimen@-\pagetotal % space left
\ifdim #1>\dimen@ % not enough space left
\ifdim\dimen@>\z@ \vfil\fi % only do \vfil if some space left on
page
\eject
\fi \endgroup}
