The real question is: what the heck bent the block out of plane that they needed eight passes to flatten it?

And, if the head is that much out of shape, how are the cylinder borings, with regards to shape and alignment?

    I can't tell from the video, but maybe the depth of cut isn't too deep. The first few skim a large part so maybe the warp in the center isn't as bad as the video makes it look. Could be over torqued bolts on ends and loose in center plus heat.
