The compressed air will drive the piston down to bottom dead center unless you have it in gear (standard trans). If it's an automatic there is no way to keep the piston at TDC short of some mechanical means. The piston not being at TDC has never been a problem for me as many as I have changed over the years. Also give each valve retainer a smack with a hammer before you start, it will make the retainers easier to get out.
