I just finished the second Gen V I have resleeved using Darton Seal Tight LS7 dry liners this afternoon. The first was done back in Dec. and is running fine with boost. No leaks.
The sleeve flange is exposed to the water jacket, similar to the Subaru EJ25 sleeves I designed for Darton. No problems with leaks on those either and I have done dozens of those jobs.
I do put a thin coat of Loctite flange sealer at the exposed areas of the Gen V block as insurance and highly recommend three of the GM coolant sealant tablets in the radiator which is recommended on any sleeved block, GM or not.
Bore size range is 4.125" to 4.185" normally aspirated. Boost or nitrous 4.155" max. bore.
The Gen V has 12 mm head bolts so there is really no need for the extra bolt holes.

As I mentioned previously the Superdeck blocks also gets doweled billet main caps with ARP main studs, the 6-bolt option, the patented truss design to stiffen the block and uses a much heavier sleeve than the dry sleeve for extreme applications.
There are aftermarket 6-bolt heads in the works already since just as the LS was pushed past the 4-bolt limit even with 1/2" head studs the LT1 will rapidly follow.
