The number difference sounds like 4 degrees advance in the grind. The difference between the lobe separation angle & lobe center is the advance/retard ground into the cam.
For the setup I would use opening/closing points, if they = 110 lobe center.

: This is a used, stock cam. However,

: Take a look at my graph and note that
: peak lift for intake is right at 110
: ATDC and peak exhaust is at 110 BTDC.
: Those are right where the specs say
: they should be. Now look near the
: right side of the chart and you'll see
: the intake and exhaust lift curves
: cross each other right before 720
: degrees. That's the crossover point
: which occurs right at 0.031" of
: lift (on both valves) at about 4 BTDC.
: I am confused because the cam lift
: points are right where the specs say
: they should be but this crossover point
: is happening 4 degrees before the
: overlap method says it should occur.
