Thanks!
The only real confounder that showed up was Dan "stock" muffler modded saw. At least from these videos, his stock muffler modded saw was as fast or faster than the ported stuff.
Also, there is nearly a 3 seconds difference between Dan running a saw, and me running the same saw!
One piece of info that I do take away from this is that the oem cylinders do not totally trounce the AM stuff, at least, not by as wide of a margin as some would say. What I also take away is that apparently there are am cylinders than are simply not as good. the uk kit and the kafar kit were just not as good as the oem 346xp or the hyway kit. I dunno why, they were ported as identically as possible.
One other thing I took away is that is difficult to do much better than stock, though it is possible to do worse
