Summit was nice enough to take the Comp Cams lifters back even though they are over a year old. I ordered a set of Scorpions from them. Now I get to wait because no one, including Scorpion, has them in stock. I will post my results in a couple of weeks. This lifter problem is probably related to the miss I have been hunting for. Here is the link to the Moparts post on that. MOPARTS 451 High RPM Breakup / Miss

oh yeah, you're right....the generic pic shows a link bar, but the description shoes "oem" under link bar....
on a magnum block are they really necessary? I've heard of roundy round guys using the stock magnum lifters to ~7K RPM...who knows how aggressive the lobes are or how stiff their springs are, though.

Or what has been done to the lifter 
true, but the stock magnum lifters I used had very little travel (only ~ .060" or so from what I could measure....about the only thing I can think of doing to a stocker that isn't more hassle than it's worth would be replacing the clip with a snap ring....

i've used the bb hyd rollers and had nothing but problems. right now i have a set of comp flat tappet hyd lifters that bleed down and are noisy as heck. they quiet down as the engine comes up to operating temperture, but they're still unacceptable. i'm pretty sure when i call i'll be told this is the first set they've ever heard of doing that. of course that'll be after being on extended hold for about an hour and a half.
