These blocks have to be bored under size and then honed to size to leave the silicon embedded in the casting, proud of the alloy cylinder walls for the piston rings to ride on.
Shortening the block will reduce or even break through the gasket deck and even if do able, the deck will be very weak.
Would not an alternative engine with the stroke/bore your looking for, be a more durable undertaking ?
