valve covers are from a 95+
Balance tube (and the dome 12mm nuts) & fuel hard line are from an earlier motor (90-93)
The coil packs are form an early motor as well.
Fuel pressure regulator & dampener are from a early 90-93 motor
Cam gears are 95 (or new production 90-94 replacements), NOT 1996

Notice that the center of the gear is the same size as the cover plate.
This is only true on 1996 NON VTC gears.
