Ed, a few proposed revisions below
Verify dowel pin in place for number eight bearing
Preinstall number eight bearing and mark a line along the case with a sharpie so you can correctly reinstall on the pin
Lightly lube oil pump internals and loctite nuts
Oil seal in RIGHT case half
Install intermediate shaft bearings
Dry-fit oil pump, connecting shaft and intermediate shaft, check for free rotation
If no free rotation, reposition connecting shaft on different splines until it spins
Mark correct position of connecting shaft with sharpie
Remove oil pump, connecting shaft and intermediate shaft and lubricate bearings
Loop timing chains around intermediate shaft and dangle through chainbox hole
Install oil pump, connecting shaft and intermediate shaft
Lubricate main bearings with assembly lube
Install pulley seal in number eight bearing
Install o-ring on number eight bearing and lube with Dow Corning 111
Lubricate pulley end of crankshaft with assembly lube and install into number eight bearing
Apply 1211 to bottom side of number eight main bearing saddle, avoid oil hole
Install crankshaft in case
Install oil pump tabs and lock nuts 900 076 025 02 and torque to 25NM- do not bend tabs yet
Verify intermediate shaft backlash with dial indicator
Bend oil pump tabs
Install connecting rod and chain props P221 and P222
Install TWO oil pump seals 999 704 172 50
Preassemble case through-bolts with O-rings and DC 111, do not tear o-rings
Mark order of thru-bolts with lead pencil so it comes off easily
Set torque wrench to 35 NM

Now, a couple observations. First, you're doing it the factory way with the oil pump first vs. Wayne's method of crank first, it really depends on how many hands you have. Second, I recommend torquing the through-bolts first because you want to establish the bearing clearance right away, particularly if you are using 574 on the bearing webs.


1104 lay out bead and spread thin around LH case perimeter, avoid oil relief!
574 rolled on bearing webs on left half

Assy:

Place LH case on RH side, tap lightly with mallet
Install through bolts with nuts on LEFT case half (same as perimeter nuts)
Torque through bolts to 35NM (25.8 ft-lb)
Torque additional case studs (timing chain housing, case side) and nuts in oil cooler flange
RESET TORQUE WRENCH TO 25NM (18.4 ft-lb)
Install case perimeter washers
Install case perimeter nuts
Torque ALL case perimeter nuts incl. flywheel and reverse to 25NM
Check that crank spins freely


Well, I'm outta gas for now, double-check all that and make sure I didn't leave anything out!
