Our engine rebuilder, AVP has made this comment to me too, and on their
rebuilt engines they do the same thing your machinist does for the same
reason (they either use AMC castings but replace the keepers, or rebuild
German heads).  Also it has also been mentioned here on the List before.
Apparantly the U.S. distributor for AMC imports them bare from AMC and
assembles them in the U.S., supposedly with South American parts. Therefore,
the AMC heads sold in the U.S. and the AMC heads sold in Europe are not
entirely the same head.

So I am now getting my 2.1 liter Vanagon heads from a source that gets them
directly from Europe, fully assembed there, rather than from the U.S.
distributor.  Lately they've been branded as Kolbenchmidt (who is an OE
supplier to VW), but in fact they are still AMC castings (as are the ones
sold by VW themselves in the U.S.).  I cannot say how long this availability
will continue, but for the time being I have a decent supply.

As a side benefit, since I am bypassing the U.S. distributor, the heads are
also cheaper than before - $369.95 each, part number 025 101 065C. These are
completely new heads, not rebuilt.

I cannot get the 1.9 liter ('83-85) heads this way, but as long as you
replace in pairs, you can use the 2.l liter heads on a 1.9 liter block.
