Should I buy this 440?

Bout dang time. lol Congrats! You got a good deal. Can you tell what year it is?
It is 77 440. I took off one of the heads today and the cylinders look okay. I don't really know what I'm looking at though. It had the original metal head gasket. I measured the deck to piston at top dead center and got .156". (I watch Nick's Garage)
