I am swapping an engine. moving transmission to the new engine. Same flywheel and the friction plate. Does the self adjusting clutch need a reset, or can I just bolt everything back on?

Yes, but there are two assumptions here. The more concerning one is that the adjustment has not moved during the pressure plate removal. The less concerning one is that the new flywheel (if you are not also swapping those) has the same design and a similar amount of wear as the original.

The self-adjusting mechanism can slip when you unload the pressure plate. An old plate is often dirty and sticky enough that the pressure of those three little springs isn't enough to move the adjusting ring. But it's prudent to have this in mind before disassembly. If you noticed the amount of extension on those three little springs before you removed the plate, and it's still the same now, just re-install. But keep an eye on those springs because the self-adjusting ring can also slip when you are tightening down the pressure plate bolts just as when you are removing them.
