This is another video that was made by Dave's Auto after the initial cast welding was shown in the original video. Dave is talking to Lake Speed about oil, and oil change intervals. He shows the block to Lake Speed after the rough grinding has been done just to get it close to the original dimensions, before machine work is done.
Link to video where they talk about the high deck IA block:

Lake Speed discusses the how and whys of ZDDP, and how too much concentration in break in oils, that can actually promote prematue wear. He also discusses that zinc isn't the primary anti wear agent, and how phosporus does more to stop wear. There is a lot of good info in the remaining video about oils, and additives.
