For my money, changing the head is easier/cheaper than changing the engine or engine/trans combo. This is most likely borne out is flat rate manuals for inline 4,5,6 cyl engines. It also needs no engine hoist.

For the air cooled horizontally opposed VWs, and some other things, the engine removal is easier.

YMMV


So which is more work 1)detaching the IP, manifold, and turbo before
swapping out the motor; or 2) simply replacing the head with a used one from
a 300TD that has the SLS pump?

 Whether it actually starts in 2nd or not may actually be a simple
 misunderstanding on the part of the PO. As far as I'm aware, all of the
 722.3 transmissions used in later 123 and 126 models stay in second when
 stopped UNTIL you touch the accelerator, whereupon they instantly kick down
 to first. You should be able to feel this behaviour by taking your foot off
 the brake at standstill and see what the creep is like vs having the shift
 lever in "L". And frankly, on most of them the modulator and transmission
are worn enough that you can feel the "bump" when it kicks down to first. If
 it doesn't kick down, the cable probably just needs adjusting.


 Do they use the kickdown solenoid for first gear start, like the W116
 300SD?
 If so, could be a bad kickdown solenoid.

 I doubt there's much to worry about. Just swap over the manifolds, turbo,
 etc from a 48 state car, maybe the IP too. At least I wouldn't want to keep
 the catalyst or those $80 air filters.
