Not picking on anybody just trying to make sense of it all i don't believe this is the first post on this issue.

I like and have used a few sets of regular Rhoads lifters
The V series lifter has a lot of advantages, it doesn’t collapse like all the other hydraulic lifters when the engine gets to peak power. The regular Rhoad’s lifters will get beat on top end power by a regular lifter because they collapse and loose extra duration, that is even against a standard lifter. A V series will out perform both, it can be a lot depending on what the cam profile it and how many RPM it turns. It is just the nature of the way the originals bleed down. There is nothing you can do to change it unless you want to bottom the plunger of the original type lifter out and set them up similar to a V series. The problem with that though is if you happen to float the valves the lifters completely loose control of the valves. The V series has better valve terrain control, and is more tunable.
