The figures are right.
You are looking at only TDC (opening for Intake and closing for Exhaust). What about the overlap in the the BDC (bottom dead centre)? The intake closes 34 deg ABDC (after bottom dead centre) while the exhaust opens 24 deg BBDC (before bottom dead centre). Is that not an overlap? Is the 58 degrees an overlap when both the exhaust and the intake are open?
Incidentally, I have an FFE on my 1.6 motor http://myfiatworld.com/forum/f23/making-ffe-234.html, and it did make a difference.
