Either one will have to be chopped so that's a moot point but by the looks of it the 24V might be able to be capped to have a smoother flow for the exhaust. In all the 12V will be easier (no need to port match and the cap is simpler) and the 24V will be a little more work.
I've not had any issues with my 12V chop but if you want to do 24V go for it.
What kind of HE351? Is it variable vane?
