There were a few different foundrys that cast FE and FT blocks. Blocks cast with the "105" reversed were cast at MCC Michigan Casting Center. Other foundrys were Dearborn, Cleveland and Geelong. Sheffield was another but was the aluminum foundry.

The story that I have heard many times over that the person that was making the mold did not put the 105 backwards like he should have, so when a block is poured you see a reverse image.
The reverse image block has more webbing in the crank area and is considered my many as stronger and better. I don't recall any complaints for any FE block used for street use.

So all 352 image blocks are not HD???
Making the non HD 352 block different from the reverse image 105.

Correct there are both std and HD "352" marked block castings from DIF. Once MCC came online all the block castings from there became heavy duty.

The only 105 block I've had with a 390 bore, was hard pressed to be bored .030. Main webbing strength means nothing if you cannot bore the block oversize.

I really have no idea sorry. Most std web blocks were slated for the std passenger cars. The HD blocks were for performance and heavy duty applications. But I've seen a pretty good mix and match of std and HD blocks in both applications in factory original cars. Anything is possible.
