New FT lifters are a 'crap shoot' as my American friends say. If you are not into crap shooting, get some 30 yr old lifters re-faced.
The Crower Cam saver lifters with a groove down the side. I have been doing the same for 30 yrs with a Dremel. No need to pay extra for it, you can do it with any lifter.
Do I thinkit helps? Not really, a gimmick, but I sleep better...
