Ok, my neighbor/uncle has a set of 1970 302 heads that were suppost to be original on his 1970 Mustang Fastback. But we got to looking at them and they are two different casting nimbers. One is DOUE-AA and the other is DOOE. What do these numbers means. I know the "DO" means 1970 but I can't figure out the rest. If I get these heads can I put them on a engine or are they too different?
