As Cobra outlined and from my own personal experience with the Yella Terra's in my LS6 CTSV; even given the added valve train noise; I will still install the Yella Terra's in my LS3 C6.
Yes there is more valvetrain noise in particular with certain higher lift cam profiles at higher RPM's, but not something that is totally unliveable.
I've been told that carbon fiber valve covers will help cut down on valvetrain "harmonics" and the fuel rail covers can provide some added insulation properties as well for cutting down on NVH.
But as stated; the Yella Terra rocker is far superior to the OEM offering and any added "noise" from the valve train geometry is worth living with IMO.
The vast majority of folks really would not even notice it and it's not worth something to let bother you and otherwise forgoe a stellar valve train product.
