I like how one end moves -- and the other doesn't -- howzat work?
When you do a stress analysis you have two kinds of things to apply, forces and constraints. I put a bearing constraint on the bore; lock one end fixed and put a force on the other end. Unless it was perfectly balanced when you put a force on both ends it would just spin. In real life the force comes on the push rod end and the tip is constrained to the valve.

It took a lot work to work through the problem. It was almost like reinventing the wheel.
Least of it was to get the head to flow and make power at that RMP. So far so good, now I have to see if the great white dyno will show the same results as my budies dyno.
Now I have to pack to go to the airport to catch the red eye to Indy. With the unification it should be a good 500! Tony
