If you are trying to compare the Hevi-13 2oz loads to pretty much any of the other 1.75oz loads out there the Hevi-13 2oz loads will kick less. This is because they are not being pushed as fast as the other loads.
On the other hand if you are comparing say Federal Flitecontrol 2oz loads vs. Federal Flitecontrol 1.75oz loads then they will be relatively close to each other, but more than likely the 2oz load will kick more.
As I said before the choke will have a very minimal effect on recoil. To be honest I'm not sure I can tell the difference between a ported and a non ported choke while shooting the same load.
