Two years is a very short life span for a valve train in a street application.
It failed for a reason, take all efforts to find out WHY ? before you proceed.
Post some close up pic's of the failed parts just maybe we can help.
I will have Brian post some pictures when he gets time. We are both pretty busy right now.
This is the 3rd cam in 7 years. The first was an unknown used hyd flat with only .460 lift, It was fine but slow, he upgraded to the comp 284XE and had 2-3 years and had 1 lifter collapse, and a couple more were on their way.
We were just talking about maybe refreshing the motor this winter, at least touching up the valve job and checking things out. We will just do it sooner than later.
