cylinder head id

hello all, just got 1 of my cars I recently purchased home today. under all the junk on the cars floor was a cylinder head [only one dang it] casting number 2406516-8. I looked it up and it came back as a 361/383/413/426 [64-67] 2.08 1.65. can anyone fill me in on any details on this head? it also had 04196 cast on it. thanks in advance Gguy PS im a small block guy and now nothing about this particular head [Maybe the other one will be in the other car when it comes tomorrow]
