Haha, your upside down pic had me wondering what I was seeing until I flipped it over.
I've built hundreds of turbos since the late '70s, and every shift shaft has a sharp raised edge where the flats for the shift lever are milled. I KNOW you didn't pull the shaft out to do this, but they should be dressed before the shaft is pulled through the case during rebuild to keep from cutting up the shaft bore. Why GM didn't spec that to be beveled is a mystery to me. I deburred all of the ones I did(before they came through the case), but every now and then I would get one in that had been driven through the case that hadn't been deburred. It leaves a nasty gouge in the bore, and usually ruins the seal if it goes back in without being dressed. Hopefully that shaft was deburred properly in the past.
I do have to ask, why all the blue silicone on the pan? Was that a problem with those pans, leaking? We never used silicone on pan gaskets, went together dry, usually cork. Looks clean under there!

The blue seal I added because I couldn’t get the cork or thin rubber ones to seal properly. I found this one on Amazon and it seals beautifully. I think the aftermarket pan wasn’t perfectly flat . I most likely didn’t need the Right Stuff sealant too , I dressed the shaft with some emery paper before pulling the old seal

New Blue Print motor helped a lot keeping the underside clean . The picture was taken after a 2000 mile trip to TN
