I had this post on here for a few years. Some of links to the pics don't work anymore because I deleted the files some time ago to make room for others. There is a pic of the exhaust ports here though. My Intakes and Exhausts measured 160cc and 60cc, respectively when I was done. I never had the heads flowed...wish I did, inquiring minds want to know. They sure do work well on my 331 though. I used a few carbide bits and an air driven die grinder and got 'em done in about 11 hours. Later on when I rebuilt the engine, I put another 3-4 hours into them to fix irregularities and do some valve unshrouding.
