But it's sleeved, I don't think the sleeve cares whats on the outside whether it's a cast block or steel plate surrounding it. Like lavon said earlier in the thread he disassembled a std. 6.7 and the billet rods looked beat up after multiple 2000+ ft lb abuse. What I understand is raising deck height gave the 6.7 combo better rod angles which makes life on everything much easier below the deck.
I'm done being a smartazz, drew correct me if I'm wrong.
Compression ratio beat up the rods/bearings. Yes the sleeves care if the combustion is moved up into the deck plate. Sleeve alone still blows out.

The deck plate is needed to hold the block together top to bottom. When we remove the stock bore material to install the sleeves we take a lot of strength out of the block. We add the deck plate for several reasons one being, we put tie bolts through the deck plate into the main web so that when the cylinder pressure is trying to blow the top of the block off along, with the cylinder head we can hold the block together top to bottom. The deck plate allows us to run a longer rod, helping to correct the rod ratio, and thrust loading of the piston. The longer rod also slows the piston down slightly, where it turns around, and switches directions top, and bottom this increases strength and durability. As for the question of running the same sleeve thickness, staying STD bore 6.7, and filling the block. I would not want to stand anywhere near that engine when it was loaded up and making power.
A 1500hp peak cylinder pressure is about the same, whether it has 14:1 or 20:1 compression. O e just requires more care of the tune, so that spike occurres at the proper time.
