4.6L 4 valve Sleeve

Just seeking some kind of idea since finding a motor for an 03 mach 1 is almost impossible. So the original block has a broken head bolt in passenger rear of the block. 1 shop said they cant pull and also saying that a cylinder is 5 thousand out of round. Would it be worth sleeveing the block and doing rods and pistons? i have all original parts for the rest of the block plus replacing the wear items.
