So the first thing is the TFS head guides. There is plenty of stories about the machining of the guides being wrong and they prematurely wear out and drop valves.
I expressed my concern to my builder and sense the springs were being changed they would inspect. I was called at some point due to the TFS rockers that I supplied were rubbing on either the valve stem retainers and or keepers.
So it was built with 4v rockers to clear.
