Probably not, the intake port width doesn't change with the lifter offsets, correct
It would depend upon where the closest point between the pushrod and the head is. If the clearance issues are closer to the bottom of the outside port wall, then moving out the pushrod seat could increase clearance there while allowing for less rocker offset at the top where there isn't a clearance issue.
Like I said, I'm not familiar enough w/ the 440-1 to know what is/isn't possible in that area.
