i did the same thing as you with your centurion when i first started rebuilding vintage bikes -- i replaced the non-aero levers with modern cane creek scr-5 aeros. at the time, i thought they would be 'better' and more, well, 'aero' and sleek. i did that on two keeper bikes as well as two flips. these were my first four builds.
then i rebuilt about 25 more bikes, and learned which non-aeros work for me and the real differeces between really good non-aero levers and modern ones.
what works for me: campy, dura ace, modolo.
these stop just as well as modern aero levers, but they require more hand force. to me, they look soooo much better than modern levers (on most pre-1985 bikes) that it's a most acceptable trade-off.
since my great conversion, i've replaced the modern levers on my keepers with campy non-aeros. record levers went on my moto and drilled victory levers went on my falcon.
