Now for the funny part.. When approaching INA at the International Motorsport Show a few months ago, they denied ever building this lifter, or even having a part number for it.

Be less concerned with the hydraulic properties, and more concerned with the physical properties of the lifter crown. The surface finish also matters, especially during break in/ work hardening. I have seen some of the replacement lifters that literally had a surface that was achieved with a scotchbrite wheel. Thats what you'll get when you pay for a cheap lifter, and its no way to achieve a proper roughness average.

I get calls about this all the time. The quickest way to cost yourself thousands of dollars is by trying to save a couple hundred. We call it "Stupidity tax" around here, and it gets paid a lot.
