There is no need to be a dick and I found your post quite insulting!
Maybe your seals were perfect but mine were not in spec!
Easy fellas! Back on track!

You mixed S4 and S5 rotor housings. The trailing spark plug holes are in a different location.
It won't cause a problem. I did it on one of my motors 8 years ago. Never an issue, fortunately.

It would not make a bit of difference if they were s5 and S4 and off. It would only matter if more then one chamber fired at the same time. Since the chambers fire 50% corolation it is irrelevant. If they were drastic on a big turbo motor it would need to be tuned out or avoided all together.
