That chamfer is direct from GM .. both sets of original GM lifters I have, have that chamfer. Not sure how it would play with modern cam profiles but evidently it was SOP back in the day.
Looking closely you can see the OEM GM has the most chamfer, the Melling has less, and the HLJ the least.
I guess it would depend on lobe profile as to whether the chamfer would even come into the equation?
