Make a record of this:
AMC is Amaedo Marti Carbonell, S.A.
Manufacturing plants in: Spain, Mexico.
US Distributor: Marnal Corp, LaHarbra Ca.
They manufacture Cylinder heads for many vehicles:
BMW, Ford. Isuzu, Mitsubishi, Peugot, SAAB, Toyota, Mercedes Benz.
They also market Valves and Guides of their own manufacture for many
rebuilders.

Thats it folks.
