The 165's are the only AFR head that will fit a stock 302 bottom end. Flycutting the stock pistons is risky business...you throw the whole engine out of balance if you try that to put a bigger head on it, and a 302 can't use the airflow of a 185 sized head unless it's spinning over about 7000 rpm.

I'd vote for the 165's or TW's. I love the Twisted Wedges myself.
