I wouldn't care if they sang the National Anthem on start up as long as they did their job and turn more than 7000 rpm and stay together.

I have not noticed any noise at start up with Lunati street link bars and rev 7500 no problem.

The cheaper set. No problems with the correct lobe, spring, rockers and lighter valves.

Guys with ls7 are turning them this hard why would these not work?

Lunati link bar lifters are Morel. But there a some differences in what Lunati sells and what Morel has.

The "STREET" series uses a cast body with machined valves inside. I believe either Eaton or FedMogul is the source for the bodies, I do not remember at this time. They also use the smaller captured roller. Those are the ones sold by Lunati. Morel PN is 5290 lunati is 72332.

The "HD" version (as I call them) use a heavy duty machined body and machined valve/etc inside. These are higher quality than the "STREET" series, but obviously more expensive. They use the larger roller and it is not captured in the case. I believe they are PN 5206.

Then there are the "HIGH RPM" ones. They have quite a few differences, but are pretty pricey. I would only use them in something that turns above 7500 really. Same as above but with different hyd characteristics to keep them from pumping up at the higher rpm iirc. I forget the pn on these, but the lunati ones may be 72532, unless lunati is marketing the previously stated "HD" lifter as these, in which case they are WAY overpriced.

I get either of them from Jesse @ Scoggin (Scoggin Dickey on here) anyway, so whatever I need, he can tell me what to get! Plus they have the best prices available for the Average Joe or the Pro Builder.

I run Lunati 5206 and I don't think they're any louder than the Caddy Racing lifters I had in there before. I ran them in my 403 and now 427 with cams up to .660 lift. I really don't spin the 427 over about 6800 RPM because it's all done before then.
