I was told to not put the gaps on the thrust faces of the piston, so I stagger the two compression rings 180 apart just off the thrust face, so about half way between the pin axis and thrust face. Then locate the two oil scrappers 180 apart and on the opposite sides of the piston skirts from the compression rings. But as moper said the rings will rotate as the engine runs. And as said your just looking to avoid ring gap alignment at initial assembly.
By the way be sure to NOT USE a band type ring compressor that rotates in on itself with an allan drive on the outside. These POS compressors will rotate the rings and make the gaps line up. Use a clamp type that use big pliers to clamp or the type with round tapered cylinders.
