302s are harder to come by than 270s. For a non-race application there isn't a lot of difference. The value is what someone who really wants one will pay. I have two 302s and five 207s counting the one in my pickup. When I was looking for a 302 I couldn't find one and settled for the 270. I don't have $200 in the rest of them. If any of the 270s have an "H" head it is worth more.
