The only way to know is to measure it. Threaded headsets vary in stack height from about 32mm to 40mm depending on brand and model. As long as the steer tube of the donor fork (measured from the crown race seat to the top of the steer tube) is at least 32 - 40mm longer than the head tube of the recipient frame you should be able to make it work. Longer is better -- you can always trim the steer tube if it's too long but if it's too short you're SOL.
