Everyones on their own with spring pressures, but I have been running the Howard's EDM hole lifters for a year, 7000 rpm at the finish line. Comp Cams MM305S-10, 279º/287º@0.050", .650"/.630" at 1.5; .693"/.672" with my 1.6 rockers 150 lbs seat, 440 lbs open (accounting for lash) Now that is almost .700" lift with a flat tappet cam!

Regardless where the hole is drilled, I can see that kind of lifter putting more oil on the cam and for what your trying to prevent....this is a good thing.
I will say this.....16 lifters equals 16 oil leaks and that means a less oil pressure down stairs.
I am wondering what the difference would be EDM vs non-EDM. I have a 528 hemi with fully grooved wide mains, H-beam rods, through the push rod oiling for the exhaust rockers and edm lifters. Oil pressure cold is 75-80 psi but when everything gets hot it is down to 20 psi at idle and I attribute this to the above. But the pressure does go up to 70 as you increase the rpms. Just dont like the low pressure at idle. I know they say use the 10 psi per 1,000 revs rule...

Then, the hole will only be in the right spot on two occasions, needing multiple holes around it's periphery to be any more effective than a single hole in the center.
Sales gimmick
The hole in my Hughes lifters are in the center.
