Under further investigation it wiped out the cam shaft during the break in???? I have never had one fail. I pulled the I take off to find a couple lifters concave on the bottom and a couple collapsed. Looks like it had an oiling issue to the camshaft during the break in. Too cold and I'm too pissed off to tear it back apart right now so I'm giving it a few days before I diagnose what happened. Before I get too much advise I will answer the most common questions before you ask. Yes, it had oil with zinc in it. Yes, I primed the oil pump before it was started. Yes, since it has magnum heads I have the oil through push rods and, lifters with oil provisions for the push rod oiling.
