First I'd like to say hello to all. I seem to be fallowing in my fathers footsteps and just picked me up a 76 f250 custom. I translated the vin# from body but now I'm onto the motor as I need to order new headers and a few other small things but I'm running into issues translating the size motor I have. I was told it was a 390 bored, but when I google search headers none seem to look similar and I'm afraid of wasting time by ordering and sending crap back. I'm coming across several #'s and here they are. C6AE9425H (top passanger side) and C8AE-H (passanger side plug area) If I could get some info and or some ideas on headers to help this newb out that would be great. it's a 76 standard 4x4 by the way.
