Machining the head is easy. Doing either the block or the liners is much
trickier to get right, I wouldn't do it unless there's a clear need. It's
very rare for a liner to warp, and if one did, I'd be inclined to replace,
rather than machine, it.
If you shorten the liners, you'll need to either machine the block to match,
or use thicker "fig 8" gaskets. Either way, you've left a booby trap for
the next engine rebuilder.
