comp. trunion upgrade problem well as most of you know my ls2 went kaput.. i was moving the heads around today and i grabbed the one that had not been damaged by the piston and i heard something come out of it.. turns out to be this
thought to myself ...where have i seen that before.. then it hit me i looked and sure enough i found this
GREAT so how did i install the rocker bearings wrong? i followed the instructions and its not just one rocker, its a few of them

How much side play do you have on the rockers? Is the center of the rocker hitting the snap ring by chance? Could be the problem, but if they are fine I would just put new snap rings on and run them.

Strange failure. I'm thinking there must have been a stress riser/defect in that snap ring. The snap ring sits in the trunnion groove and there really isn't any load on it besides it's own spring tension. Look in the groove on the trunnion and see if maybe there's a flaw/protrusion in the groove that might have caused stress on the snap ring.

It is more than one rocker tho... Some are broke on both sides! Just glad I found it now instead of when I was having to pull my head again to replace a spring or even have to rwbuild the motor... This is truly strange

How long has that Trunnion Kit been installed?
I'd say this is wrong. Obviously there's a problem and simply replacing them may not fix the cause of the problem. Replace them and cross your fingers it doesn't happen again?

And like raven154 said, you may have spread the rings too far during installation.

The rockers have been upgraded for over a year and my cam specs were 230/238 .600/.604 112+2... I hope it was just the snap rings being over stretched because my new cam is beastly compared to my old
I don't know about that stretching them too far comment. They are meant to be expanded for installation just like any snap ring. But it is possible they were a defective bunch as most snap rings are very tough and hard to break like those did.
