Before getting too involved with changing things, take the time to make very careful measurements in re: action dimensions. For example, check out the following: From the book, "Steinway Regulation" by F. R. Deitz Point of hammer center Model S -B C-D from underside of string 4.6 cm 4.9 cm Point of rep. center 11 cm 11.3 cm Blow 47 mm 47 mm Dip 9.5 mm 10 mm underside of keytop from keybed 63 mm 65 mm You will want to look at the deck height (key bed to underside of string, nominally measured at the factory at note 62) which should be nominally 7-1/2". Everything works backwards from that measurement. So, to the extent that it is too "proud" (it is usually too high, as against too low), you will need to refigure the measurements from Dietz. Be sure to check the spread - spread pre 84 was 4.381" and post 84 was 4.395" I think that you will find some good information on all of this published some time ago in the Journal by Chris Robinson.
