They were still ok but so long as I had bought new ones gaped them I put the new ones in.
Assuming you do not drive it much, fuel cost is not very important. You might visit one of the air fields and see if they will sell you aviation fuel-not sure if it is legal.
RE: 14 to 1
You likely have a single four barrel carb on that. In 1963 no one cared about pollution. You fuel air mix was and is not constant and it gets leaner in the cylinders located further away from the carburetor
