Uncle Tony says Gen III hemi has inherent lifter lubrication problems. Agree?

Interesting that he claims that's its NOT a lubricating problem as far as volume, but a problem with the amount of "stiction" of the oil. Very interesting. Of all the 5.7s I have replaced in my shop, ALL of them had delamination, and zero appearance of a lack of oil.
Just curious, what is the average cost one could expect to pay on a cam/lifter replacement in a shop??? Not asking for your exact quotes, but ball park.... thanks
