Vitus 992 Crankset question. Dura ace 7410?

I am looking to replace the BB on my vitus 992. It currently has a bb with a 111mm spindle length on it (was used as a single speed by previous owner), however I wanted to replace it with a Dura ace crank and BB along witha full DA group. The chainstay seems to already have a bit of chainring rub on it with a 111mm spindle length, and I have been speaking with Chombi for advice (he's been fantastic btw) and he has told me that 113mm is shortest for double cranks and suggested I reference sheldon's BB sizing chart.

Now, I came across a 7410 crankset "low profile" (what does that mean....) at a decent price and with some research noticed that the spindle length for the crank is 103mm, I am not too sure that this will work on my frame given the chainstay rub from the previous 111mm spindle. I checked Sheldon's chart and it does say that 103 is indeed the correct spindle length and it gives a 43.5mm chainline. Given the infamous flexibility of the 992 BB flex, should I be worried about chainring rub if I run the shorter 103mm spindle? I am just a bit confused as to how this all works out, do the 7410 cranks jut out more at the square taper area to help push the crankset further away?
