First I must say hello to all I'm new here. I just picked up a 92 5.0 H.O. from the bone yard. i pulled off the valve covers to see what type of heads are on the car. The motor had Crane roller rockers. with an eldebrock water pump. I'm just getting into fords so I don't know where to look for the information I need. Anyway the number appear to be 31875 they were casted in a circle . The other #'s are 2f22 and 2f19. i figure the second set of numbers may be sometype of date code. The only other information are the letters cp the are about the size of a nickle.

So there is nothing under the valve cover that will tell what heads you have? That sucks because I just found 4e19 under my covers and I was hoping that would ID them. Since I am not sure what my motor came out of.
