Those are the heads I'm talking about (C9OE-E), the ones I have. They aren't listed anywhere. But are supposed to have 58.2cc chambers. Just cleaned them up and I'm going to try and cc them soon to make sure. From what I understand they had a about the same thing for 1970 but were different marking.
They are in Bob Mannel's Small Block Ford Guide, in fact if it's not there I'd be willing to wager it did not exist, at least from '62-'69... It's a fantastic piece of work, main issue is he stopped at '69 so none of the newer stuff is included... http://www.fordsmallblock.com/cgi-l...69.html?L+scstore+yyxf4628ffdfbedf+1415965295
