Solid Lifter
I had the Morels and they worked great and used the strock lifter tray.
I previosuly had the Comps back when they had too large an oiling hole. had the oil hole been the correct size i would have preffered the comps. They have a link bar connecting the two lifters to keep the straight. And they were very very light and had a short body. . I just called Comp and they now have thier newly redesigned lifter PN 8956-16. I havent even seen a pic of them yet.
I think most serious racers with no budget use Jesel though. But I belive they are pricey.

Verdad Gallardo something needs to be used to keep a lifter from turning in the round bore.
The stock lifter trays use flat spot on either end to keep the lifter oriented correctly.
Lifters that do not use the stock lifter trays must use some other device to keep the lifters oriented correctly...most use a link bar between the two lifters on that cylinder. that will keep them from turning during engine operation. The flat rollor riding on the flat cam alone is not enough to ensure the lifters orientation. Especially on a solid roller where there will be loss of contact between the two surfaces. Any slight turning would tear up that cam surface in a hurry since the dge of the lifter roller would impact the cam.
BTW...Ill have a new set of the Comps here in a few days. Ill post them up when I get them.

383LQ4SS, thanks for the clarification. It all makes sense now. 
So if I already have a set of new lifter trays for my new motor, should I stick with the regular Morel hydraulic lifters, or do away with the trays and use the new Morel lifters due out in February?

Here is Comps new solid roller lifter PN 8956-16. I have no idea how much and they dont seem to be in a catalog yet. But I belive if you call Comp direct you can purchase them. they are alot like the old ones but there is only 1 oil hole per lifter and its oriented towards the center of the motor (rear of lifter). Should work fine. they are very very light and short body. And I prefer a link bar as well.
no...they will stay in place just like the stockers....if they did slip a bit they would just slide down a little. Im not sure if you could get the cam in there and spin it as you go in to get the lifters back up or at the worst use magnets on the ones that dropped down a bit to get the cam in.
You could definately do a cam swap without removing the heads and there are 0 worries of droping a lifter in the block.

LSM or Jesel if you want a Bronze Keyed lifter that is beyond amazing in performance and price.
Otherwise, the Crower High Pin Oilers (HIPPO) are very good on the street. The current Morels do not provide this, but the revised ones will for the LS1.

I'm looking for the best option for a max effort naturally aspirated 415/416 L92 engine. I thought I was set on the regular Morels, but now this comes up and throws me off. Are the regular Morels not good? Should I wait for the new version to come out and do away with the lifter trays?
