Aluminum blocks always have sleeves whether gas or diesel. I think the block in that picture is a Dart BBC.
Not always.
Chevy early aluminum V8s had a coated aluminum bore.
I don't recall what the coating was called right now (something lame sounding, I remember that much) and it didn't last worth a shit.....but they used it that way for like 20 years.
Just googled...
Nikasil
It's ceramic spray in shit.

Its nickel plating. Works good on two cycle engines.

BMW tried Nikasil for a while. They changed to Alusil afterwards. Alusil is another form of unlined aluminum block, but it seems to actually work.
