Telling people w/o any experience to alter the short side radius is just wrong IMO. You seem to think that no harm can be done to a cylinder head regardless of how much is hacked out of it. You (should) know better.
If you were "passing out" anything of real value other than green lighting hogging hell out of a head, then you'd send each of these people templates that could be duplicated in brass, of all the important radii/sections of the ports. In this case, I don't even see good photos- which leave a lot open to interpretation even if there were a hundred of them.
