I think if you change the belleville washers from ()() to (()), you will get the drag you need while still getting freespool when you move the lever back. This is not hard to do on a Penn.
You can use alantani's rebuild thread for the Penn 30S to help you.

The 80 will not be much different except for having 2 drag washers instead of one. It should help you change the bellevilles and also teach you how to make the spool bearings spin better by removing the shields, blowing all grease out of them, just lube them with Corrosion X, and then reinstall with shields off.
When I rebuilt our old Penn 50SWs per Alan's tutorial, I changed the bellevilles to (()) and was able to get better freespool by doing the bearing cleaning and also bottom out a 50lb scale at strike while still having good freespool with the lever back.
Good luck,
