I don't get it. Yes, when you put a sleeve in a 440 you hammer it down to the bottom and "seat it". It has no register on the top to keep it from going up and down if it wasn't seated. But everything I've worked with that had "real" sleeves has a register on the top. The OD dependent on the bore spacing, and the depth of around .250". The block is counterbored .250" and you put the sleeve in that also has a .250" register. Now this isn't rocket science. You stick a sleeve with a .250" register in a hole that has a .250" counterbore and the top of the sleeve will be flush with the deck. You can verify this by running your finger across it. I bought a new Indy block once. The sleeves were about .002" below the deck. I was afraid that wouldn't seal so I decked it 003". Again, this is basic math. Either the counterbore was too deep or the sleeve was cut too thin. So much for Indy's quality control. So I don't have any idea how the sleeves in the video could "settle".
