Farmall H/ super H differences

[Brockpend]

Can anyone tell me the difference in a farmall H and super H manifold?

Sorry I don't know if the manifolds will interchange ? I do suspect it may be one is all fuel and the other gas only. But in terms of power between the 2 models it is night and day difference !

If comparing between gasoline and gasoline the flange where carburetor bolts on is the main difference. Same when comparing a kerosene and distillate manifolds. Aftermarket did make some manifolds with slotted holes so H and SH carburetors would fit. Used bolts for mounting instead of studs like originals.
