GTX is right. If you put gas pistons & all fuel pistons side by side they're the same height.
The piston pin holes however will be in different places!
Gas & all fuel connecting rods are the same but when pistons are attached to 'em, the distance from the center of the crank pin to the piston face is greater on a gas than an all fuel giving it higher compression.

Mostly just your call. Gas pistons made of aluminum will make it much snappier. It will then be a gasoline only tractor. If you go original with all fuel iron pistons it won't have as much HP and will be able to burn most any petroleum product that will flow through the system long as your shutter still works. Sometimes they're easier to get to idle smoothly with gas pistons than with all fuel.
