This is why the liners "drop", they don't in practice, they have simply deformed the newly annealed block.
I suggest this is the point where a replacement block is sourced, shimming the liners is not a cure for a block which has been overheated to this extent.
If you do decide to carry on, you will find the liners will "sink" again, this is especially true if a MLS gasket is employed as part of the repair.

And the god of da k series ha spoken.. get a new block, skim if necessary the build and forget!
Don't waste time & money on a suspect block, do it right, first time.
