I think you are right. So do I expect bent valves at this point? Seems like I would not because the valves are opening and closing exactly opposite on one bank.

So, off the top of my head here is a fix for this screw up. please review and comment:

Step:

1) Lock the engine at TDC with the 4-6 side cams in the position where they can be locked

2) Remove cam chain tensioner for the 4-6 side

3) Pull the oil scavenge pump in the engine compartment

4) Remove the cam sprocket

5) lock the cams with the cam locking tool

6) Unlock the engine and carefully rotate the crankshaft clockwise 360 while feeding the cam chain over the inlet sprocket - likely get a piece of plastic to put between the chain and inlet sprocket teeth while rotating

7) With 4-6 cams locked into position, re-install exhaust sprocket

8) remove cam locks and torque sprocket

8) tighten up tensioner

9) replace scavenge oil pump

10) replace cam plugs

So - what's missing? How can it be improved?

I'll take the easy missing piece - unlock the engine!
