I dont know the actual differences in the cylinder heads themselves, thats if there is any like porting etc.....
look round in the forums and u should find something on the two types

the difference between the different year models of the 400 head i imagine as you suspect are simply superceding part numbers. the valve dimensions, and lengths are unchanged between the years to the best of my knowledge. It would still pay to compare as best you can by sight the external bolt locations between the heads of all 3 years that are in question in case there have been other changes.
