In my opinion, GMPP is exercising poor judgement by not casting the LSX block out of aluminum. If it were me, I'd cast a few of the current design LSX blocks out of aluminum being careful not to shift the cores. CNC the block for sleeves, build it and put it on the engine dyno for torture testing. It's not a big investment, because it just a material change (aluminum) with the addition of sleeves.

I know you guy don't like the World Products stuff, but you could at least mention the existence of a decent aluminum LS7 block. Yes, I'll put the flame suit on...
BTW I haven't heard of one of their blocks going south that isn't builder related.

If I remember correctly the world tall deck block has a slighter taller deck height than the other versions out there. I think it is a 10.2, but I could be off a little.
