Squareback vs round back alternator?

I have learned so much since starting this project ( 1975 Dodge Dart Sport ) .1) If you stroke a 360 and use Eagle H beam rods you have to notch cylinders for rods to clear . 2) if you use a cam that requires roller rockers you have to buy pushrod checker and get right length plus have machine shop elongate holes to clear push rods. 3) If you use Edelbrock aluminum heads a squareback alternator won't fit must use roundback. I am not done yet still lots to learn .
