Good to hear your son is helping.
When you say a loss of contact between the rocker and the cam lobe, I am going to assume you mean, as the cam profile decreased, the valve stayed open, the rocker was loose, and then the valve closed some and took out some slack?
Please explain exactly what was happening verse what should have happened. Intake or exhaust? During opening or during closing?
My first thought is the valves are sticking in the guides, maybe?
