I would think it be less.
Full benefit of 58's would never be seen on a 103 - 107...few on here have 58 w/ their 103 kit and I wonder if HD just did it so that they can just say how big of a tbody they really are running.
All that room open for air but heads don't back it up.....nobody can tell me that an HD 103 are good enough to flow enough to support the 58.
EDIT: by HD heads I don't mean the stock of course, instead the SE.

on the tq side,it would be less.you`ll probably pick up a couple HP way up high as long as the heads can support it,not something ide recommend unless it was a very aggressive build for high RPM power & heads flowing in the 310+ @ 28" area
