The chances of the lifter wearing out the cam lobe is very small, unless the roller seized up.
Check your harmonic balancer. If that'* messed up you will get vibrations. There'* a rubber area between the inside and outside, if that rubber goes bad it will vibrate.

I still need to explain the noise that'* coming out of my engine while revving above 2000 rpm though. I think I'll replace the lifters and then go from there.

One thing I have seen with roller lifters (in 2.5 GM eng) is that the lifter can get turned
sideways, and the roller wont spin anymore, but will eat the cam lobe. Not sure about
a 3800 doing that.

IIRC, 3800'* have lifter guides that prevent them from being installed any other way or from turning on their own.

I just found this.
The lifters are slotted on two sides.

There'* no way they could have turned without breaking the guides. The guides were intact.
