Yes, that's good, also expensive, but maybe not necessary. On the other hand I'm not sure if this could be done in a big bore V6, for space reasons.

The problem is that in the Alfa engine the liner is supported near its bottom part, and in other engines, like the Ferrari 575 Maranello (which have aluminium+nickasil liners) the liner is supported and centered by its top part, this way it is not necessary to leave extra material to the liner over the block deck to compensate the different thermal expansion of the materials, because the expansion is absorbed by the sliding of the bottom part of the liner inside its crank housing… (I suppose is clear).
