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.
