When you see cam bearings getting smashed down, there is an OILING issue. Don't know if your restricting oil or something, but there is no way those spring pressures would drive the cam into the bearings like that if they had oil.



I used to run 360 pounds on the seat with new springs. I also grooved the number 2 & 4 cam bearing journals to get oil upstairs all the time. The cam bearing a always showed witness marks from the groove in the cam on the bottom of the bearing.


The next upgrade was going to be roller bearings on number 1 and 5 cam bearings. I sold it all instead.


Anyway, you have an oil issue.
