Which lifters? So I'm about to do my head cam swap on a 2005 GTO ls2 and I started thinking about lifters. Originally I was going to use stock lifters, but I've been thinking it would be good insurance to change them. I'm using LS3 heads with a 226/234 .598/.612 cam with 7.400" pushrods and heads milled .024". I'm planning on revving the motor to 7000rpm, shift point is at 6700rpm.
I heard that the ls7 lifters are the exact same as the ls2, and there have been mixed reviews about problems with them.
I had the cts-vR racing lifters recommended, but I read a few threads where they had problems, but the threads were from 2008.
Lamar Walden machinist told me that they have had problems with the comp lifters(who recommended the CTS race)
What lifters do you guys recommend that won't have problems? I already have the pushrods so it needs to work with the factory pushrods basically.
I did a good bit of reading but it was inconclusive.
Thanks,
Ryan

A customer has a 2010 LS3 Camaro M6 trans with the Comp LSR 227/243 cam. The new LSL lobe is very quiet compared to an XER type lobe. And barely any low RPM/Load surge.

ok so it looks like the consensus is I should use Lunati or Morel lifters. Since my cam only has .612 lift should I use the link-bar or drop in setup made to work with the trays? Once again revving to 7k rpm and have patriot dual gold .650 lift springs.
My budget was $350 for lifters, and it looks like the Lunati's are around 700. I found the morels but which one should I get? Thundar racing has them from 400-900. Whats the cheapest way to get the best lifter? I know morel and lunati are basically the same thing. Are those ISKY lifters also morel. Which are cheapest and where.
Also do all these lifters work with stock size pushrods? My pushrods were ordered when I was still going with stock lifters.
Sorry for all the questions, I'm definitely still a noob. Thanks for the help!

Link bars are added security. You do not want to drop a lifter at 7k into the bottom end of a motor.
As far as lifter recommendation Morel lifters are made in the USA - you cannot go wrong there. Morel does manufacture for Lunati (who also uses PBM), Isky, Comp, Crane, and a load of others. Alot of times certain companies will make their own internals and Morel will sell the bodies as a supplier to the retailer and the retailer to the customer. I know Comp-cams and Crane are two that are said to be this way.
Isky or Comp are my two personal favorites. Lunati's get alot of mention but i have ran them in an LSx platform so i cannot vouch.

I agree w/ the notion that link-bar > plastic tray, but let's not invent failure modes. The tray fails, the lifter rotates in the bore and chews up the cam lobe as well as itself.

How exactly does a lifter find its way into "the bottom end of a motor" when the plastic tray fails? Is there even a single example of this actually happening?

Link bars have always been an added notion of security IMHO - individual applications vary. Simply words of advice - nothing more nothing less
