The first thing I would do, is pull the action, check the key bed for trueness. Place action on a "Flat" surface to verify that it is warped. If the keybed is ok and the action frame is, in fact, warped upwards, then a fine saw kerf can be made in the appropriate areas, (of warp), and fine hardwood wedge shims can be glued in. This is one of those jobs, where you do a little, test, do some more, test some more, etc, etc. Hope this helps, Regards Joe Garrett, RPT, (Oregon)
