I aquired a 1969 C9OE 4v motor. I am gonna use the shortblock for a buildup. I have heard that the heads on this motor are an awesome, low-buck upgrade for a 5.0. Anybody using these heads. The seem to be in good shape. I am going to use my Victor Jr., so I willl probably sell these............what are they worth? How about the factory iron 4v intake with spacer, or the "powered by ford" stamped steel valve covers. Is any of this stuff worth selling?
