I would check to make sure the old springs are within a couple of pounds of each other at the installed closed length (with rotators). install one, measure installed length, then compress them to that length on a scale. (or have them checked) If they are close, and if they stand straight when on the bench (do not lean over more than 1/16" measured top to bottom), and if they all stand to the same height within 1/32", I'd use them with out hesitation. At under 2000 rpm, it doesn't take much of a spring to pull the valve shut reliably. Heavy springs can wear cams, lifters, and rockers. Good for racing, bad for long life at normal speeds. Use the rotors, they keep the wear even around the valve face, and add life span to the rebuild.
Good luck with it.
