Do I need an alignment after changing these suspension parts?

[lizem100]

2001 S 430. At a tech session I replaced both front upper control arms and both lower front struts. Part numbers 220-330 57-11, 58-11, 94-07, 93-07. The techs helping me did not think I needed an alignment but had to ask around. Does anybody know for sure- Steve B in FL, M. B. Doc, Larry Bible...? Thanks.
If anyone else wants to do this same project make sure they have TWO 16 mm wrenches and ideally one ratchets. Also do not be afraid to administer stout blows with a heavy hammer to jar the old parts loose.
