That was an install into a '99 Grand Prix using a Dorman upper, the Dorman reduced diameter stovepipe, and a sleeve from Bill. The sleeve was not attached to the stovepipe.
These pictures are from a 00 Grand Prix using the original GM UIM, and a stovepipe with sleeve attached provided by Bill.
In both cases, the stovepipe is closer to the intake around the 2 o'clock position. However, in neither case was it so far off that I was not able to install the bolts for the UIM through the manifold and gasket, and into the LIM.

Have there been any problems/leaks with this gasket offset in earlier installs
with this problem? Looks like there isn't any apparent solution to this offset...
My plan is to disassemble present assembly....look closely as I go back
down to block and go from there...
I plan on reassembly using torque value of 11 ft lbs/132 in lbs on lower
using LIM torque pattern provided in this post..FSM DOES NOT even
illustrate torque pattern..it shows upper...it is totally USELESS in this
maintenance procedure....
Any other input...pics, thoughts are more than welcome...
Thanks again guys...

I believe that it has been 2 years since the work was done on the '99. That was my son'* car, and there hasn't been any issues with any leaking. The 2000 (my son-in-law in 2 days) was done this past winter. No issues so far.
I don't believe that your torque setting for the LIM really enters into the off-set problem here. Using the pattern for the LIM would be ok. Using a large area like that, you'll almost always see that the pattern follows a "Z" pattern, starting in the center and working your way out. I do it in about 5 steps, on both the upper and lower. First time, 1/3 the torque setting, second 2/3rds, full torque the third time, and then twice more around to make sure it is evened out...but I've been called "anal" a few times.
When it comes to the UIM, when it came to first starting out, I start out the opposite way. When first putting in the bolts, I start with one or two on the throttle body end, and then a couple at the PCV end. Just thread them in a couple of turns, and then add the rest of them. All went in without an issue. Then I'd thread them in just far enough to contact the UIM, followed by torquing them down in steps.

good and half a$$ed mechanics. I got a couple of thoughts about the lower I will
keep to myself until I disassemble/reassemble.
On the upper I started on PCV area {seated} to position the upper and then
followed APN illustration....All bolts dropped right in..felt right...
Thanks for input/experiences...and special Thank-you to Bill Buttermore..
