   I have a set of 350 heads for my 72 motor. The casting number is MP1243452 which I think are from 1974. Does anyone know what the cc's are and did they change from earlier models?
   
   Thanks, David

   According to www.atlantabuick.com - the heads have 58cc chambers. I believe the big difference on 350 heads, was the valve sizes.
