An "L" shaped ring requires a very different groove machining detail on the pistons. That should be immediately noticeable if you look at the piston. Also, are you saying you have 3 rings for each piston or 3 rings for the kit? neither would make sense. Haven't seen Wossner pistons in person for that engine, so don't know what they are using.
