76,68,64cc are probably the most common. average intake runner I think is around 170cc. I think you can get 185cc ported but that's stretching it.
The casting number will help give you an indicator but it's nothing positive with what you exactly have.
You will need to cc it yourself to be sure. Several rebuilds of the heads can make 76cc heads to 74's etc.
