Look real good at the block pass side right below the head. That's where they leak. It's probably not the head but the block has cracked. I would walk away if it's a 53. Unless you have a good block laying around to swap.

 

A verified cracked block would make the value of unit very low. Dealers, used car lots and auctions will make their value very attractive for a do it yourselfer on engines. JMHO

 

Stay away from the 53 block i bought one with it and i am hating it everyday i look at the truck sitting being a garage queen.
