If the geometry is correct, lift not going to matter. As long as the duration doesn’t exceed 200 at .200 lift thats when the issue manifests itself. I doubt his hydraulic roller was.
Here’s what I did fine to be a issue, I’ve found 2 blocks that the lifter bores had hair line crack. Remember certain lifter bore are attached to the block like a cup handle. 2 and #6. I think #2 let go on his block.
