The worn lifter I posted the pic of is an EDM lifter.
They’re still the same normal thickness as the non-EDM pieces.
.135” in the very center in those examples.
Also, there aren’t EDM hyd lifters.
It’s hard to pump up a lifter with a hole in the bottom of the pressure chamber.
I’d be very curious about just how thick the bottoms of his lifters are.
Although it’s probably a moot point.
That lobe and lifter were toast long before the hole appeared.
