I think the mid to late 80's Campy shifters (C Record era) had the same size cable head wells as the Simplex Retrofrictions.
I'm planning of using my Dremel at slower speeds with an abrasive drum tip and roll the heads against it to reduce the head diameters....very carefully....
Trust me - buy the $9.99 brake+shift cable kit, it's worth it.

No grinding. Way less painful. Plus bonus brake cables + housings and shift housing as well, ferrules, stops, the whole 9.
For the shorter cables, the way they wrap the housing up it leaves them a bit wavy. A couple of good tugs or a little blow dryer heat gets them straight if you use them.
