I dug out an old Chevy/GM performance parts book. and sure enough it showed 66 CCs. I also found where I had CCd those heads many years ago after AFR did them, they were 68 CCs. I just had them flat milled the absolute min. to get them true [cut .013] but have yet to CC them. probably first part of this week.
I also had one cyl. flowed to get the numbers and they flow pretty good for old iron heads.
thanks for the help guys.
