The fork is a real nice old Ritchey that's even signed by its maker (!) so I'm a bit loathe to cut it. What does one do?
Several 2mm aluminum spacers will cure your problem. See examples below.

LBS.
Cut down the steerer??? HUH! Me thinks thou hast been breathing the rim cement fumes too much!
VERY SIMPLE SOLUTION... Headset spacers, been used for years. Common issue BITD when folks switched from center pulls to side pulls. Back then nice polished chrome plated spacers were hard to get so people used black or silver stamped steel spacers.
As gugie mentioned nice aluminum spacers are readily available in black or silver in 1mm, 1.5mm, 2mm, 3mm, 4mm and so on.
7 threads of engagement provide the maximum strength in most threaded applications. I like to use a minimum of 5 threads or 5 rotations on headsets.
1" keyed spacers for classic British or Italian headsets. BTW, I stopped using these because they tear up the threads when they rotate out of the keyway slot in the steerer while tightening. Use a pair of spacers without the keyway tang (file it out or just use the aluminum spacers).
25mm spacers with a flat for French & metric headsets. Those steerers have a flat cut or ground on the top threads.
1983 Trek from the factory with multiple spacers.
3 each 2mm spacers.
Frames made after threadless headsets became popular tend to have longer than necessary steerers. Striped black & silver spacers on a long steerer. I don't cut them off unless absolutely necessary because down the road, may not be able to get a proper fitting threaded headset.
Headset Stack Height measurements.
Easy way to measure the steerer to determine Stack Height capacity. This steerer has about 40mm of capacity.
