I'm pretty sure ford didn't make heads with a cc ranging 3 different sizes. Maybe someone on here knows cc size for e5ae heads
The D8 head is a 1978 model and the E5 head is a 1985 model.
I seriously doubt they are compatible, but I guess it is possible.
They seriously are not worth your time and will gain you little if anything over a set of E7 5.0 heads.
