I can comment on some things. Since I was not there, and was not involved in any way I am only equal to the rest of us - I am a spectator with no skin in the game.

The valve contact - I can see why you would get the impression that the valves rotate from viewing those parts. Its more a matter of the where/when/how they contacted the piston though. Once a valve gets hit the first time it is no longer flat and every subsequent contact can move it, spin it, fold it and mutilate it. There is simply no functional design element that causes a valve to rotate in operation beyond the nominal "scrub" from the spring.

As to the Coon heads I can only repeat my personal experience. My experience with the heads has been acceptable, my experience with the man behind them is challenging. I know that Jay has had a significant personality and legal conflict with Coon and that may color the tone of his discussions.

As for the component selection - I can only restate that we do not have enough repetitive experience to say "those parts always work, but those always break" on Cammer motors. We all use a small selection of parts from a very limited line of suppliers and while we are developing, the pace is slow in comparison to high volume builds.

The business situation and relationship between the various parties and how they handle it is none of my damned business.
