Brand has less to do with it than cam profile, spring pressures, and oil choice. I stuck a Comp Cams stick back in the motor.

I'm now convinced the last oil change I did utilizing store brand oil and forgetting the zinc additive was the culprit. Due to all the cylinder head issues I was dealing with, I had changed oil numerous times in the past year. Got tired of putting in the expensive oil. I cheaped out one time. That's all it took. With the aggressive Comp Cams XE lobe profile, it didn't take long. Like the subject says: expensive lesson.

There have been NUMEROUS articles on cam failures over the last several years. Really not necessary to rehash it here.

I've got Comp Cams break-in oil in the motor now. I'll probably use the Brad Penn Grade 1 going forward.
