You can only squeeze so much battery capacity into a space.
Theoretically, two 6V in series and two 12V in parallel of the SAME physical size will have the same voltage and same cranking capacity. There should be no discernible performance difference between the two layouts.
Electrically, it makes no difference if you have two 6V, 1000CCA batteries in series, or two 12V, 500CCA batteries in parallel.
One distinct advantage of two 6V in series is that if one battery goes bad, it doesn't take the other one with it. When batteries are in parallel, they will tend to balance each other out. The weaker battery being charged by the stronger one until both batteries are the same voltage.
Another distinct advantage of two 6V in series is that there are only three standard cables. Two 12V batteries require four cables, or two specialty cables.
These days there are single 12V batteries that will work just as well as two 1960's era 6V batteries. With only one 12V battery, you are down to two connections so it's much easier to maintain.

Today's Featured Article - Tractor Hydraulics - The Basics - by Curtis Von Fange. Hydraulics was one of the greatest inventions for helping man compound the work he can do. It’s amazing how a little floor jack can lift tons and tons of weight with just the flick of a handle. What’s even more amazing is that all the principals of hydraulic theory can be wrapped up in such a small package. This same package applies to any hydraulic system from the largest bulldozer to the oldest and smallest tractor. This short series will take a look at the basic layout of a simple hydraul
