On our 1977 LUV Mikado, the timing chain chewed into a water passage that is molded as part of the aluminum timing chain cover. The dealer we had the truck into in 1982 replaced the head (which had tested as good), head gasket and rings BUT did not fix this issue, thus $1,400 later we still had a water-in-the-oil problem (lots knocking, lurching, lots of white smoke!) until WE found the problem ourselves because we were too broke to let these "experts" continue.
I do not know what year your truck is, but if your timing chain was rattling at all, pull the timing chain cover and check if the integral water passage has been breached by the chain. It may not actually need a full rebuild, just a flush-out and a timing chain cover replacement (tighten the chain, too).
We've been doing most of our own work on our truck ever since, a dealer shop manual for the 77 LUV is worth its weight in gold. (We asked for and retained the parts that were swapped out, most of these are probably fine.)
Good Luck!
