Richard, In the 85 version of Sutherland's I find this: Record Strada - stack - 39.1 22 x 3/16" balls. Record Pista - stack - 33.7 25 x 5/32" balls. Note: different number of balls. Stack is upper + lower minus thickness of locknut lip. Also if you have a Gran Sport instead of a track headset it is also a lower stack height than Record, much closer to the track dimensions.
