OK so I bought a pair of what I thought were cleveland heads at a swap meet. The guy told me they were clevelands so I figured they were. Come to find out, I take them apart and there is a WF casting on them, so I figure that is for Windsor Foundry. So it turns out I have windsor heads now... No big deal. I have looked forever and reasearched head castings and I cant place one casting. The casting is C9OE G. Here is what I know from decoding it for myself. The C = 1960 Decade / 9 = the year / O = Fairlane / E = Engine Department... BUT I DON'T KNOW WHAT THE G STANDS FOR... Any help at all would be appreciated. Thanks alot.
