@ando377 you're talking like it's a 70s V8.
The cylinder liners crack, you can shim the block, add a cooling plate/brace or sleeve the block.
If you have the engine out and want to run big turbo I would recommend these open deck sleeves from elevate as there the easiest to fit/ least amount of machining Pistons/rods are pretty stout but you can go to forged rods and 8.5:1 pistons from rs/s60r
