302 heads - differences

[coralcoupe1993]

Hey all! Havent been in here or messing with anything Mustang in a while. Manly been playing with old stuff and Big blocks. I am messing with a 72 right now. Has a 302 with some burnt valves. I have a few sets of heads here. Just wondering if anyone has casting numbers or know off hand the differences. Wondering if I should redo these heads with hardened seats or if I can smack a set of E7s on it and go.

Let me know you have some 302 head knowledge.

Just throw the E7's on and go. A 72 won't make shit for power anyways. Got a real nice complete 331 if you want to really wake it up!
