I have an alloy windsor 9.2 deck Dart block, built by KC, these blocks are good quality and dont give the thread problems etc like some of the old 1960/1970/1980 blocks. Plus I cant emagine the sleeves moving down the block especially when the motor engineers do this work all the time, and follow the correct procedures, surely if the sleeves are seated properly and I am not sure if the block is heated up to further assist this process, and then machined true, there shouldnt be any problems!

Further to that driveability improves, even on the road because you dont have to move the same amount of weight, especially on a road with some nice corners, and the cost isnt really that much more than a new cast iron block, in my opinion buy once and get what you want, and get a reputable engine builder.
