Big Block ticking? Flat tappet cam. Normal?

With Father's day weekend I might not get to this, but I will redo the valve lash and check it out. I was worried about dead cylinder and wiping a lobe on the cam. But since the lash specs are close, probably not the case. Unless they all wore equally after less than 100 miles on the new rockers. I will post an update when I find something.
