also the 255 and 302 look the exactly the same on outside
so make sure your getting a 302 a 86 and up or 87 if its a high
output would be best because there is a lot of improvment over the older ones and the ho comes with trw forged pistons straight from ford you dont want an 86 unless you bore it because it comes with flattops with no valve reliefs wich limits cam choices
and the heads suck to. just tryin to help you out a bit.
