One of the DOHC's gears may interchange with the SOHC. (The DOHC will have 2 gears that are both a 2:1 ratio to the crank, for those who would argue otherwise.)
So if the SOHC and the DOHC both have a 18 tooth crank gear, then they'll both have 36 tooth cam gears, the only difference is the DOHC has 2 of them.

Good thought, it's conceivable that the DOHC application may fit and work just fine on the SOHC, but based on different part numbers for each application (both OEM non-adjustable and aftermarket adjustable) it almost for sure won't work the other way around. (Maybe a wider timing belt or something??) I'll have to look into it, but ...
What I have is two running cars, one resurrectable (close encounter with a deer) car and one spare engine that fits the resurrectable. Only one of the cars has a 2.0L DOHC engine - the running 1999 Escort ZX2 2dr 4sp Automatic. Only one of the cars has a 2.0L SOHC engine - the running 1999 Escort SE 4dr 5sp MT. The resurrectable 1994 Escort LX Wagon 5sp MT and spare 5sp MT transaxle are both 1.9L SOHC (same as 2.0L but different bore and emissions). I hardly drive the ZX2 - just enough to keep the battery charged and the seals wet. It's my insurance against the daily driver (me or the car) suddenly needing serious repair. In the case of the car it means I still have something to drive every night while I do the repairs myself. In the case of myself, it means a broken or badly sprained leg, arm, wrist doesn't put me temporarily out of a job. The short and sweet is I'm not tearing into the engine of the ZX2 to count teeth, until the Wagon is backup and running.
