73Mav, Old Guy is correct!!! He didn't get old making stupid decision!! Teasing you Old Guy, but I think you are right on the mark. If you get a set of 69 or 70 351W heads you will get the street performance you are looking for. These heads have larger valves and a 60cc chamber. The 78 and newer windsor heads are the same as 302's. 1971 and newer have larger combustion chambers. The casting dates you are looking for are:
DO0E or DO0Z for the 1970 castings and I think C90E or C90Z for 1969. I'm leaving a link to a set of heads that sold on ebay, in that add he posted a picture of the different head castings and chamber sizes. The heads have long since been sold but the info is there. I suggest you confirm my date codes, I know that Ken Merring, who posts on this board frequently would be able to help. http://cgi.ebay.com/ebaymotors/aw-cgi/ebayISAPI.dll?ViewItem&item=593284396%20&r=0&t=0 Good luck, wm
