Its not a seat you can see the picture it is the top or bottom ring of a valve spring retainer keeper I have found many in the pan over the years even in the pick up screen.
Yup....To all you people who thought it was a valve seat.... how in the **** can it get in the oil pan without a hole in the m'fn piston...
This is the cylinder that has the piston in upside down. No loose springs etc.

Let's get pictures of all of the cylinders and the whole head(s) so we can see what is going on... Otherwise we may miss something...
also get a picture of both heads with the rocker arms removed... The whole head and then some close ups of areas that look different...

Valve lock seemed possible, but they dont look missing in the pic.
So what about a piece of pin boss, or how about a ruler next to the debris so we can give a more educated guess here...it could very well be the bottom of the locks...they do look deep in the retainer

WBecause the OP didn't POST A PICTURE OF A ******* PISTON.
That's why I hate pictures that are shot out of context, video with audio that is a best a guess.
The OP should have posted much more than he did. This is how bad information gets out there.
what other pics you want I will send 100 pics if that’s what you need just looking for some advise not trying to start a pissing matchBecause the OP didn't POST A PICTURE OF A ******* PISTON.

Ok thanks appreciate the info already called machine shop taking down to bare block.Don't worry about yellow rose, he starts pissing matches with everyone.
At this point it doesn't really matter. That engine should be completely torn down and gone through. With that kind of damage, those kind of mistakes and that amount of metal floating around it should get a total rebuild.

Sure looks like the bottom of the keepers to me. Didn't someone state that in the begining? LOL Sure the motor should come apart. I would replace the pistons so that means new rods due to the fact their cheaper to buy then resize, Rods , pistons, bearings, Gasket kit, oil pump, heads are cheaper to buy then rebuild,
It is hard to say.... the valves may well be bent and we can't see it with that shot. No matter; it comes all apart.Either you "missed" on matching the head to the piston or someone has been in there since the valve strike, those valves don't appear to have hit that piston. Sure you didn't flip something and take a picture of the wrong chamber on the head?
No I don't. But MO was WAY out of line with his comments. I'm not taking that **** from anyone.
That wasn't directed at you. It's problematic with looking at pictures on a computer.
Had those of us who said its a valve seat insert seen the Pistons it would have brought another answer.

You probably have a good block and crank. And all the accessories needed to make a healthy 340. We just went down this road with a customers 340. He was a friend and we cut all corners to save money on the build. Good Edelbrock heads are $1300. price out Valves , Seats , Springs, Retainers, And then all the machine work to install those parts and resurface the heads. You'll get just as much into those heads and you still have 70's cast iron heads. Less then $4k everything new. That was with all the machine work and assembly.

The left hand rocker in that pix of the rockers looks really chewed on the left edge. And boy, yeah, those keepers look down deep. Wrong retainers? I've never had ones with the - offset so cannot say on that possibility.
Not to be discouraging, but be ready for a boatload of new parts OP. This looks to have been thrown together with whatever was laying around.
