Looking to raise front end

Front suspension is an area where I know nothing. I'd like to raise the front end of my '68 Fury 4-door. When we go over speed bumps everyone except the driver has to get out of the car or we bottom-out.
I LOVE the soft, swaying boat like handling. Don't want to change that. I've read that you can adjust the torsion bars to raise the front end but as a result the ride is much stiffer. I prefer the soft, don't feel any bump in the road ride.
Has anyone ever put a lift-kit...
