"I found the keepers to be very soft. I have gone to Buick exhaust valves with as much contact area in the stem keeper interface area as I could get, new keepers, new springs. I had the same problem last year on the exhaust side and it let the inner spring lock up in the outter spring which then locked the bucket. When the cam lobe came around it shattered the bucket. Again the good mechanic up stairs looked upon me and NO serious damage was done. I plan on running the car this summer than I'll check the keepers for wear."
