These are AMC heads that have been "re-badged" and re-boxed.  I got several
sets from a certain supplier not too long ago and I sold them for the same
price I would normally sell AMC heads ($395 each).  They may use different
valves than the AMC heads as we are not sure if they are sent to K-schmidt as
bare heads or complete.  If it gives you a warm fuzzy feeling to try to
pronounce a German name, then go for it.  If not, don't get too excited.

PS.  There are no bids on this item as of this morning.  The starting price
is $600 for a pair of heads (that is a good deal since they would normally
sell for almost $800 for a pair).

Thanks,
Ken Wilford
