Have you inspected the cylinder walls on that cylinder for scuff marks that would indicate a broken ring and the piston for damage that would not hold pressure? Also is there a problem with the lifter, push rod or rocker arms on that cylinder? You dont give enough detail. Where did the replacement head come from?

could be a cracked head, a cracked block, or as i have seen very recently, an erroded coolant passage in the head itself that over laps the head gasket. all three will give similar results.
