I'm not very knowledgeable on 348/409 stuff, I was told that they were 425hp heads. He bought a pair off evilbay for $2600 to get the customer's job completed. They think the thief was looking for BBC stuff and simply picked up the 409's mistakenly while stealing in the dark. The dork also took a new box of 4.5" bore pistons and 8 mismatched rods.
