The face of that lifter was ground with less precision than I grind a buggered up screwdriver blade. Unbelieveable, You could literally see how "cupped" they were from sloppy machining.
For you quys who may not have been around on the good old days when OEM lifters were available, they were micropolished and the corner the video spoke about was sharp with no excessive radius.
