LS2 lifter chatter

I'm having a bit of chatter from under the hood while under load. I assume its the lifters and/or springs. Im in the process of aquireing the new parts to rebuild the heads and new LS7 lifters anyways, and while im at it a cam. Does anyone have any insight on what it is that I'm hearing?

OK, the reason I ask is because, yes A LOT of LS owners report it but almost everyone says something different. I wasn't sure if it is in fact something to be concerned about. I appreciate the response.

Could be a produce of the typical overhead V8 valve noise, but if you could post a audio track, that would be helpful to verify your noises.

Believe it or not, i added maybe a quart, of Lucas synthetic oil stabilizer (full synthetic) and wah lah, noise gone!! I think everybody's right about once your pushing over 500 you deff need a thicker and tougher oil. RD/LA
