Those 5-6 hours will include 2 or 3 trips back to BC with questions. If you rule those out by research ahead of time, cut it to 3-4 hours. 
A mere 9-beer job.

Prep and tools are key.
If you had a tub of parts cleaner.. you would remove the LIM and drop it in. While you are cleaning the gasket surfaces on the block and heads, the LIM would be self cleaning.
I use a 3m scotch brite cleaning pad on an airtool. Cleaning of heads/block and LIM gasket surfaces are now down to about 20 minutes in total. By hand..you could spend an hour or better.
Have the torque specs printed out and taped to a wall or something. Remembering that GM misprinted their FSM'* for a few years and the UIM torque is less than the LIM torque.

I'm 53 years old and with my wife holding the trouble lite, 2 grand kids complaining, and a 9 month old 100lbs.black lab barking I don't think I could do the lower without FLIPPING OUT and having AAA towing it to the junk yard half-way thru the job!

Bob, it really isn't all that much more work for the LIM. You'll be doing everything again sometime in the near future to replace the LIM gasket if you don't do it now. May as well get all the "pain" out of the way at one time. I'm older than you are with similar distractions (no Lab) and managed to accomplish it. Set aside a weekend to do it, so you can take breaks and work at a leisurely pace. You'll have all the help that you need for clarification on any problems right here. You'll kick yourself later, if you don't.

myself <-----
...and a mechanic i paid broke it down to the LIM gaskets down in about 25 minutes 
...so think about that in reverse. it will probably take a little longer being meticulous as you go. i would say about 2 hours at the most.
