Not Ranked
Rick,
He has admitted in previous posts to turning (or trying to) this engine to 8000 rpm on many occasions.....therein lies the problem....
Parts do weird things at higher rpms without proper reinforcement and blueprinting....he's seeing the result of that.
The valves do look worn, that's why I told him to check the valve guides. With all of the wear on the parts, I'd say the guides are catching the brunt of it.
