You don't need gorilla torque for manifold bolts.  If you do, you have more problems to deal with.

 

Now, the pinion nut on a Dana 80, that's gorilla torque...

I just laid under the truck with a box end wrench to get all of my bottom ones.  That said I have long skinny arms, so that likely helped.  It would be way easier to just remove the airbox and come in from the side.

Was you exhaust still there?  I'm thinking that dropping that first would probably help, and you do have to at least disconnect it anyway.

Yes, I did it with everything in place with the wheels on the ground.  I may have used some sockets too, I don't particularly remember.  I know I used a ratcheting box end wrench on some, and had to install a bolt in the back hole as the stud and nut had backed out completely and was missing.  The front lower stud may be easiest to reach from above in front.

OK I got after it again today and finally found a combination of body position and tool, and got to the last two manifold bolts.  All are snugged up now.  The last two didn't really need much, maybe 1/4 turn.  No change.  Truck is still very sick.  But at this point  I have eventually found how to touch each of the bolts, but I'm not yet convinced I have the reach or expertise to get them all back in if I were to take them all out since 3 or 4 of them I got a wrench to, but not my hand.

 

Actually put the back up on stands so the wheels were not touching the ground and looked underneath while it was running.  Still cannot find a leak.  I did check with a local shop that said, for $200, they would do a full diagnosis and tell me what is wrong.  Given the amount of time I have spent and not found the problem, I am considering that plan.  I'd feel a lot better about trying to pull off the manifolds if I actually know that is where the problem really is.  Or it's at least possible they will find a problem that is easier to fix.  At some point my Advanced Shade Tree Mechanic degree isn't enough!
