.060 preload is way too much and the lifter will collapse if set that much upon pump up.
If you do not believe this, then call someone who builds LSx and uses them frequently.

Here's a quote which doesn't need to be masked...

BTW no masking needed, ask Louis at LGM.

When I talked to LGM about using Comp R lifters they told me there was no need for adjustable rockers.
But when I called the Comp tech line they said I don't know who told you that but they don't know what they are talking about, you must use adjustable rockers to even get the benifit of the R lifter, its designed for and should only be used with adjustable rockers.
So, as far as information goes this is what I got.

Hey fellas, I thought my post I started was asking for what to look for on my lifters, such as defects, damage possibly, things of that nature, not a argument on preload between two other members. I have already decided awhile ago with previous posts to just keep the factory lifters, I just wanted to make sure before I put the car back together the lifters were okay, since I've bent valves,busted seven rockers, scuffed the tops of my pistons, just was hoping I didn't damage any lifters. Thanx. 
I can appreciate your passion with your LS1's, that is why I have come over to this sight. To learn.
