I've never raced or had hands on help on any brand aluminum drag race motor so I'm repeating what I've heard or been told by those that do race them, other brand non Mopar aluminum blocks

Ok, but what if i find my sleeves have moved up above the deck? My block has all of the rotating assembly in it, cam included. Can i just heat the block and torque the head down to press them back in?

I don't think they will rise above the deck.

Call the block maker and ask them if the sleeves are suppose to be above the block .002 to .003 cold so they will be flush or a tiny bit down with the motor running and warmed up, The KB Street hemi blocks were designed that way back when I built my street hemi block in the early 2000s

When i purchased the block the sleeves were .003 above the deck. Best Machine decked the block, but i have no way of knowing if they reset the sleeves before hand. Doesn't mention it on the receipt and they are no longer in business. The sleeves in this block only have a .001 interference fit, so they move easily with temperature changes. I should be ok, i'm just being mindful of the situation. I now understand the French gentleman in the video had that block polished and the block was recleaned after, heating the block and allowing the sleeves to move. Steve missed it and they had that sleeve drop issue.
