I had been forced into doing it, several times... as above, easy enough to pull the block off either with pistons disconnected inside the block or block off leaving the pistons hanging around.
For re-fitting, oil baffles not returned, if the engine has been over-bored then the conrods can be carefully slid down the bores and it is easy enough with a piston ring compressor. If the bores are at standard, the conrods will probably not go down, so fit them in the block on the bench, pistons at the top of travel, re-fit and connect 1 & 4 or 2 & 3, carefully rotating the crankshaft to correspond first with your choice, once the first pair have been connected, carefully turn the engine over to connect the second pair. The key is not to re-fit the oil baffles.
Quite a painless way of doing this!
