Lifters with bars, not trays? Hey all looking for some new lifters cause I think I have a collapsed one. In looking around Ive seen some that have connecting bars instead of trays, is this a good thing? would it be upgrading to go to this type of lifter?

Yeah, the bar is just to keep them from turning when using roller lifters in a block that was setup to use flat tappets. Without the bar, the roller lifter would twist around and the roller would be damaged, if not the cam lobe also.

The trays themselves.
Notice the flat part of the tray in this picture. It lines up with the flat portion on top of the lifter.
Note the flat part at the top of the lifter.

Sorry about the size. Just easier to see this way.

Yep.
Sorry, I went back and edited my post to show a pic of the tray. Huge lifter pic added.
Take notice of how the flat in the lifter corresponds with the flat portion of the tray.
Kind of like a keyway.

You'd better hope your friends lifters could NOT be "spun" as you describe it. If they could the damage that was done would more than likely prepare than engine for the trash pile. You're mistaken when you say the "lifter spun". If the "lifters spun" you'd have a lot more than just some bad trays to deal with. Do you know what a "flat" is and I don't mean an apartment in England? The lifter has a flat and the tray has a corresponding flat. This is what keeps the lifter roller in alignment with the cam lobe on the LS series. Next time you help a buddy tear down an LS you might want to do some closer inspection of the lifter/tray relationship or have your buddy explain it to you.

We sell a lot of Morel with the link bar to LS1 owners 
Its a superior lifter and the link bar is better than the lifter cups. The lifter cups have failed on people, most of the time its when people do not change them when swaping engines and re-use the old ones. Its a plastic tray. Doesnt happen very often but it does happen.

Direct swap. Morels are excellent lifters, but they command a high price due to the better materials and superior tolerances that are held on the internal components. They are also designed to ride lower in the lifter bore as a result of aftermarket cams having a smaller base circle. Crane billets are also excellent lifters, but to my knowledge are not available in a link bar design.

I had a lifter turn. I think it was because it came down too far in the tray due to the high lift cam. Ended up tearing up the cam and shortly after spun a bearing. I ended up going to the crane lifter that is a little longer than the stock lifter and most other lifters (expensive). I think the morels are slightly longer as well.
With all the talk about heavy valvetrain and valve float, is the weight significant enough to cause valve float in some applications?

Well, I am all ears on this one, as I thought you had to run the trays as well. I am new to the LS game, and have a motor at my machine shop right now, and we are going solid roller. Now, I know that a roller motor has to have something to prevent the lifter from turning, and I know on all my small block Fords I ran, when I converted from hyrdaulic roller to solid roller, we changed the type of device that held the roller from turning. On the Ford, when it was hydraulic there is a bar that is held down by the infamous "spider" tray, and when you convert over to solid roller you do away with the bar and "spider" tray and run a link bar on the solid roller lifter.
So, you are saying essentially the same can be done to the LSx? Inquring minds want to know.
