On replacement pistons (actualy ANY piston of which one is not familiar with) then check for wrist pin OFFSET. Not all pistons have any offset. Some do. SOme don't. IF any wrist pin offset exists then fit the piston such that the wrist pin is setting closer to the THRUST side of the cylinder wall.

The slots are ffor thermal expansion of the piston. The slot should be OPPOSITE of the thrust wall of the cylinder.

In any case, it will be wrist pin offset that dictates position of the piston regardless of a slot or no slot.
