were undamaged i would consider sleeving the block and using the pistons over. i would probably do all 8. i dont know if it is a good idea to mix sleeved cylinders with unsleeved on an aluminum block. maybe you can get aluminum sleeves, and then you could just sleeve the bad ones.

it might be cheaper to find a good used engine.
