You mentioned 'Rake' - mast rake or rudder rake? It seems like 83 was the first year for adjustable upper rudder casting. With these you can rake the rudders forward to alleviates some of the helm you feel. It's still there, you just don't feel it as much. The 'On the Wire' archives mentioned, did indeed have some great articles on rudder improvements. If you do have the adjustable rudder castings, and they're not working, then you'll probably need to re-work and re-tighten the rudder system to make them more effective.
