Lets think about this logically. The symptoms are:
1. Weak performance
2. The right exhaust is not as warm as the left
3. There is oil in the right header pipe.
What problem can account for all of those symptoms?
Tight valves won't cause the oil in the pipe.
Ignition problems won't cause the oil in the pipe.
Carb issues won't cause oil in the pipe.
Leaking valve guide seals might cause some oil in the pipe but usually that oil will be partially burned, not pooled.
Stuck or broken rings will account for all the symptoms and will be confirmed by a compression and/or leak down test.
There is no need to confuse Spacemanspiff with other issues that can't be the cause of the issue. It is a simple diagnosis problem that can only be confused by becoming parts changers and using the hotgun approach to it.
