I was told that a 250 DG aluminum head for an odyssey will will on my 74 CR250M. If so, which year of Odyssey's will work?

the head wont work without mods because the mt and oddy have 1 5mm stud and the cr250 has 4 5mm thuds in the cylinder.the combustion chamber might be all wrong for the cr250 motor as well.
