Which set of older lifters had the problem with the oil band in the wrong place or was to narrow only allowing part time oil pressure to the plunger?

I found that to be a non issue. Those were Johnson's by the way. Had this discussion many times and posted pics of the 2 sets of lifters side by side, and with tom S's help determined which were which. One set I ran was Johnson's, the other set were the S lifter from shafer. All from comp supplied at different times.
Oil bands were drastically different heights. Ran both in a 455 and both were dead quiet with lash set properly, hot idle oil pressure 40 lbs.

Where things go sour with this stuff is poor bleed down rates due to sucky quality control. Morels are known for this, just depended on who was supplying the lifters to the cam manufacture at any given time. Hylift Johnson's are typically preferred, people just don't want to pay out the nose for them now. Son just paid $1140 for them and are now over $1600 since they had a price increase. It's why the new evolution lifter is becoming popular and so far good success.
