For future reference 60degreev6 site has this and pretty much all the other info for the 60s, the CR calculator will tell you combustion chamber sizes.

Re: V6 Cylinder Head Chamber / Valve Sizes.

Gen 1 Iron heads are 48.5cc
Gen 2 Aluminum heads are 26.4cc
Gen 2 Aluminum "Turbo 3.1" heads are 27.4cc
Gen 3 Aluminum heads (3100/3400) are 28.6cc
Gen 3 Aluminum 3500 heads are 32.4cc

I don't have the valve sizes for the gen1 engines but other than the early carb heads they are all the same like project89 said.
