You need to determine if those pistons have an offset wrist pin. In other words is the pin located closer to one skirt than the other. If it is, then the shorter side of the piston goes on the thrust side of the cylinder. Easiest way to remember which is the thrust side of any engine is the connecting rod points toward the thrust side of the cylinder on the way down it's stroke. Some use offset pins, some don't, no set rule. Generally engines are designed this way to reduce any chance of piston slap noise.
