***UPDATE***
So I just got done with replacing the rocker arms and this is what is going on:
New rockers
good oil pressure
bad part there is a loud knock from the valves or pistons.
I'm uploading videos

ok I'm no expert.. but that sounds like rod bearings to me.
I'd say that thing is hosed man.
I went with a salvage yard Lq4. It was cheap, but i'm not so sure i'm gonna stick with it just yet. LQ9 would be better if you're gonna stay NA. Bit harder to find but still a great choice. 400-450WHP easy.

it makes that noise because of slop as it is my understanding. the piston rod is banging around as the crank moves. Eventually the bearing will come loose, bind against the top bearing and lock the engine down. Could damage the block. best if you stop now, take it apart, maybe the block is still good.
what worries me is his earliest ticking noises are similar to the sound my car has been making for about 6 months now. think mines just noisy valvetrain though.

Mine started as possibly rockers. Well I dont know if it want to do a total motor swap..my best bet would be to just leave it off.. open it and see what it is..bc i just want to get it running so i have transportation. If it is a spun bearing can't I just replace the parts?
