I have a Comp XE285HL that is failing. .545 and 241 247 @.050. Im running 1.6 rockers for .581 lift. I am running the valve springs comp recommended. I have about 1k miles on the combo. I started noticing a lot of lifter/rocker noise. I found this on tear down. Ive never see a cam wear like this. Any ideas?

It was broke in with driven breakin oil and mostly valvoline vr1 10-30 oil. I think I did one oil change with amsoil 10/30 high zinc oil. Filters were wix . Ive never seen a failure like this. Im going to a solid roller and I want to make sure my bases are covered.

You might contact Comp and see what they say but that cam is wiped. How many miles are on it? And you know you will have to pull that engine apart to clean out all the metal debris....and check bearings etc, etc, etc....
