It's anyone's guess what they'll flow once they've been ported, it depends on how well and how much porting they've received. As for stock numbers, look here http://www.jason.fletcher.net/tech/flowdata/castiron.htm


Also it depends on what year they are. The newer 351 heads weren't as nice as the earlier heads ('69-70). Those earlier heads were very similar to the original GT40 heads.
