FWIW, I just sold a rebuilt set of heads, magnafluxed, milled .010, new guides, new seats, valves and springs checked and replaced as needed, new seals. Total price in the swap was $350. That was exactly what I had in them. However, I had no receipts to verify work.
I could have gotten a little more if I had receipts...
Stick around on here a little while...you will get a buyer. Welcome to the site!
