Fresh engine, wiped cam? Tick? (new pics added)

My engine has about 250mi. There is a pretty loud tick on the top end at the #8 cylinder. I have a feeling that the cam is wiped. The exhaust manifold seems fine.

Since this is a pretty fresh engine, my money situation is now nothing, so this sucks. I am thinking about just getting a couple of new lifters and placing them in for the #8 cylinder, and see if that fixes it first. IF it doesn't, my guess is that it would be the cam. Now... If it is the cam I am kind of afraid of metal floating in my oil, but I don't know? Since there is so few miles on it, do you think I can get away with just installing the cam, and new lifters?
I know I SHOULD tear the whole thing apart and check everything. As I say, I'm a poor boy right now.

Am I on the right track? Is this what you would advise doing? I did have a shop quote me $1500.00 to tear it apart, and clean it out and place it together again. He figured since the heavy work is done (like the heads) 250mi ago, that $1500.00 would be about what they would charge. I don't have the room to do the complete engine myself.

I have options here... but what would you do? What could I get away with?

Thanks much!
change the cam too too many flat tappet cams going flat these days
use comp break in oil or additive new oil sucks now days used to be only chevy cams went flat....
