Yes, for regular lifters you will use four of the same trays.

Yes, I would have no hesitation using summit lifters
I say get all 16 summit lifters and trays. I trust Summit as a vendor.

Ok. I went with the Summit lifters and I think I finally have everything I need ordered. I'm gonna spend the weekend getting the front cover off, getting the oil pan ready to come off and do some more cleaning on the block. Last thing I need to do is send the computer out for a re flash. Can anyone recommend a place? Thanks again everyone for all the help and advice. I wouldn't be able to pull this off without it.
This guy will do it for $50: https://lt1swap.com/afm_delete.htm
Others here have used him with good results.

I did the flash myself using hp tuners.
A little bit of a learning curve, but I found it more interesting that way.
the downside is you need to buy the dongle + licenses.
you will need a minimum of one for just the ECM, and they run about $50 each.
The link above is a much better deal if you're looking for easy + cheaper.

It's like I said in my previous novel- Summit doesn't manufacture their own parts, at least, not lifters. They also wouldn't risk their reputation on slapping their label on junk. They're big enough in notoriety and sales volume to strike good deals from whoever supplies GM with the parts they install at the factory. Like their "Summit Performance" LS head bolts, valve springs, rockers, etc., I'd suspect them lifters are Delphi or whoever actually manufacturers them.
+1 for lt1swap.com for your AFM disable. Note that they don't do any custom tuning. They only remove AFM from the programming. A bargain, IMO, for the ~$60 invested (once you factor in shipping to them). If your cam will work on a stock tune, then you're all set.

They are different. Here are the AFM trays (note the different hole sizes and ribs)
Non-AFM:

And the lifters I linked are "Morel #7717" but with the summit branding
Slight upgrade from the standard "LS7 Style" lifters you normally see.
I had issues with too much oil bleeding off, and with my pac springs they caused me issues with prelash.
those "Morel #7717"'s are a straight .050 preload if i remember correctly.
but you will want to verify that.
Other types it varies from .050 - .100
talk about a pita if you have a set of AFR heads like myself.
I also took mine apart and cleaned, inspected, etc.
I found them to be excellent quality, super tight tolerances too.
Pay special attention when you take your lifters out, look what direction the oil holes face.
they should be the same type and can either face away from the main oil channel, or directly into it.
if your using stock springs, I would just clone the current setup.
For high seat pressure/double springs, I believe the instructions were to face the holes into the main oil gally to help keep them pumped up.

Chris, after all these years you think I don't know about AFM trays! LOL I meant that I don't know if there are different trays for regular lifters, the question posed was do GM Performance lifters use different trays. I didn't think so but never even thought to look. But then again my memory is going bad! Who makes those braided brake hoses you like again? LOL I already forgot and you told me the other day! LOL
again.. you might never have a issue. but just incase.
the failed Amazon on the right, looks like a old school Delco bag. on the left is from the dealer, newer light blue bags

I meeeeeean... I thought it was an awfully novice question on your part. But, we all have some small bits we've never delved.
I see the "GM Performance" branding as just that- the brand name and the lifters are standard LS7 or "LS7 style" lifters that are used in all the engines and not anything different or "higher performance". So I read the question as "Do you know if the trays are the same for the stock non AFM lifters and the [also stock] lifters?" Which, now makes your reply make more sense. Didn't mean to step on your toes!

Thanks man. Just ordered them off Amazon and they claim they will be delivered overnight by 8am tomorrow which is crazy. I verified they are GM genuine. I'm gonna keep the AFM trays I ordered since I suspect I might need them when I start dealing with my 08 Yukons misfire. Just an FYI the Amazon AFM trays I just got where legit GM genuine parts but you have to look real close when ordering. A lot of vendors are trying real hard trying to disguise knock off parts as GM originals using deceptive phrases and copying GM part numbers.

So the question now is do I put it in or keep my 170,000 mile original one which has never given me a problem whatsoever. I've been messing with both my trucks so much lately I honestly feel I could pull the intake in like 20 minutes so if it does go bad it's not the end of the world.

I'm going with the 12689035 OEM GM cam which I believe is the stock non AFM cam so I should be good as far as tuning. Just need to verify push rods are the same.

That's a smaller LM7 grind with VVT. Cost you about 10-15 horsepower.
These are the cam grinds in your two trucks:

https://www.summitracing.com/parts/nal-12638427 = I have this cam.
I love it.
It's the stock 6.2 cam, has tons of low end.
ETA: Reviews state it "might" require a valve spring upgrade, so you will want to verify that the valve lift is compatable.
I think it is with the stock 699 heads... but again verify.
And I used 12689035 my first go around.
Lame cam, I lost power from the stock DOD camshaft.
Run away.
