I totally agree Keith. I know it's been done many times before but there just isn't enough documentation and pics to convince everyone that it's easily possible. I know for a fact that there are many Early A owners who would love to use large "great flowing" manifolds but don't want to buy something that might not work or that might require to much additional work. I think many of the Early A owners don't mind making some modifications but most them would prefer "bolt in" manifolds (like most of us).
