What Bogie said^^^

Engine was either over revved, or run with the valvetrain adjusted way too loose.

Whether it was the previous owner, or you who did it we cannot say.

Those two missmatched pushrods do say the previous owner may know something about the situation.

The wire clip that holds the internals into the lifter broke at some point in the past, the installed pushrod would keep the pushrod cup and the rest of the lifter internals from coming loose until the pushrod is removed, then the internal spring in the lifter pops it out.
It couldn't have been run wiht the plunger popped out like that, because it would have a dead miss.

That was your noise. Good choice to pull the intake.

Look at the the face of the lifters as they come out. Seeing this is a relatively fresh engine, the lifters should pull out of the bores relatively easily. Check the the flat faces for concavity. None should be worn excessively, if that is indeed the the case, then Johnsongrass has the best plan IMO. Just break in the cam to the new lifters as if this was a brand new cam install.

I appreciate you guys alot . This has been a real learning curve for me to always just build my own motor and don't buy a used one unless your gonna rebuild it or tear it down before you buy it. Just noticed something else some of the valve stem tips don't look good at all gonna put a photo am I gonna have to dig deeper ? Also a picture of the lifters.

Looks like pushrods may be too short... but as Eric says, just a guess from here...

Any engine I don't know the history of, I consider it as a core. I get offers all the time of guys wanting to sell me an engine that was just "rebuilt".

Long ago the big companies replaced "rebuilt" with "remanufactured" insinuating EVERYTHING was done right for the long term... but then some started using 'new', but inferior quality Asian parts that became available...

Valve stem picture focused at wrong distance so can't see the tip clearly... too short a pushrod may be creating excess movement of the rocker across the valve tip... that's what the videos above try to avoid...

One lifter bottom definitely 'looks' different from the others... but it may be OK... lifters aren't actually flat on the bottom, but microscopically out convex in the center to allow oil get underneath... should never be concave...
