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!

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.

THe s4 housing will knock before the s5 housing. The s5 chamber will also have lower emissions than the s4.

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.
