Darton wet sleeves are $2,600 installed at R.E.D., and will require the use of special coolant. Between an LS1 and LS6, the LS1 is the only of the two to sleeve, and wet sleeves are the only reliable sleeving method for the LS1. The LS6 crankcase breathing windows under the cylinders carve out important supporting material for the sleeves, which is why the LS1 is preferred.
For the price and coolant issues involved with an LS1, you may also consider an LS2 dry sleeve which is $1,670 installed at R.E.D., but add to that the cost of the LS2 block and covers. If R.E.D. supplies a new block, the total cost is $2,750. This is what I would do if I had the budget. I'd love a 4.125 bore and 3.622 or 3.26 crank, with caddy racing lifters and Harland Sharp rebuilt rockers, the thing would rev.
Some people are considering resleeving L92/LS3 blocks, but in the L92 the sleeves are not always straight. A few blocks need to be sonic tested to select a good block for resleeving, so if you have a new L92 block it doesn't mean it's good for sleeving.
Add costs of packaging and shipping the blocks around also.
