I bought a 00 gt already 4 valve swapped, the motor was locked up when I bought it. I pulled it out and noticed one of the cam bridges was broken. I have been searching online for a hour to figure out what head I have. The casting number is RFXR3E6C064B F, The head has a 99 circled and ford cast into the side. I believe it is a 99 c head but I'm not sure. The block is a 93-98 teksid. I know their not b heads, I have a set I pulled off another teksid block. Any help would be appreciated
