Junkyards, maybe local 4x4 shops, pull a parts, eBay, and just look on line. You can find ones that have been cleaned up and polished for $230 or less. At a junkyard it depends on the condition of the part and advalablility and how much a shop will charge you to clean it up and make necessary modifications the head itself.

I have a worn out 4.0 head that I can have rebuilt. The price after putting in chevy valves, welding the water passages, mill the head square again, and setting spring heights it is the same as what he charges $525. And my head needs valve guides also.
