340 damage dilemma

I've decided not to sleeve this block and gamble on the outcome with my limited dollars. Maybe if I could pluck a handful of $100 bills off a tree in the backyard I would go for it. There were a couple other factors involved in that decision as well. The block itself has no sentimental value to me. Already acquired a 360 block and crank that look to be in great shape, setting at the shop awaiting hot tank and magnaflux. Thanks for the input.
