P5007140 Mopar R/T cylinder head

Hello all. I'm here looking for information. I'm in Montana.
I have a single Mopar R/T
P5007140 cylinder head that I'm trying to find a home for.
It was used on the Dyno and for tuning my Dakota R/T. I had these and the 2.02 set and went with the 2.02 heads instead.
I don't have the other head.
I sold it years ago. What are these things worth now?
And if anyone wants it just make me an offer. I'll have ups box it up and ship it but it'll probably be expensive to ship.
