As a sidebar, the performance manuals and articles recommend swapping the pistons side to side for more performance. Do you swap the whole assembly or just swap the pistons on the rods for the offset?
You run the pistons backwards, turn them around on the rod......however, that only applies to factory pistons whose pins are offset. The offset pin from the factory was used to help put a "load" on the piston so they would not rattle so much. Turning them around backwards "unloads" them and frees up a little friction and does have benefits. It's an old racer's trick. Modern performance pistons have the pin centered, so there's no need to run them backwards.
