New 6.5 cylinder heads

[CoyleJR]

I have a set of new bare cylinder heads p/n 12522533 still in the box. They came with a dead 6.5 truck that I bought in 1998. I replaced the motor and never needed the new heads. I think it is time to clean out the garage after 13 years and sell these heads. Can anyone supply any details about what these heads will fit and what a fair price would be for them.
Thanks in advance.

Assuming they are heads designed for civilian use, they will work on any 6.2L or 6.5L engine. If the stainless-steel pre-cups are of the large port design, they would work best on a turbo engine, but they could also be used on a non-turbo engine - if giving up a little in fuel economy.

What they're worth?.. I've seen complete (w/valves & springs) new AM General heads go for as low as $500 each, but $600-900 has also been paid. But, these are GM heads, which didn't have the advantage of Navistar's updated alloy and design changes made for AM General. They're still worth quite a bit, but perhaps not quite what new AMG heads might be. I'd guess $500 for the set would be a fair price. I'd start there...

Hope this helps...

Did you ever sell these heads? I'm in the market for a set. Do the pre-cups have a diamond in them? What is the casting date? Pics? Thanks.
