Cam wiped out, what the hell did I do wrong?!?!?

Did you run it at a high idle for 25 min when you fired it?
Kept it 1500-3000 for 30 minutes.

did you see if the lifter rotate while went the engine is turned over..?
Yes, when I turned it by hand. I didn't have the rockers on, so they weren't under any pressure when I checked it. Could that give me a bad indication?
