The 4M806 manifold was used on the D320T engines such as the 922 (59A loaders)
8H6877 & 8H3197 are exhaust manifolds for the D8H
2B3313 manifold was used on the 22 fuel system change over from tractor fuel to gasoline
9M444 = 6H8986 is an 8mm injection pump used on the 4-1/2" bore engines.

Thanks Old Magnet, hope you are keeping well, it’s been a while since my last visit,
I guessed the big manifolds were D8 but I don’t have any books to confirm that.
thanks again
