Well, this is embarrassing...but it has to be said.
The Crower lifters that went bad, was entirely due to user error. I initially set the valve lash completely wrong and ran them that way for about 20 minutes. Even after correctly setting them, I still did not realize my previous error.
Now I have to measure each lobe to see if the cam is still good...but I am fairly sure it is not, just by the sound.
On the bright side, I have an Isky 280 mega cam and a Comp 290b-6 solid cam on the shelf to choose from. Either should be a significant performance improvement over the 60919.
From now on I will be setting my initial valve lash with the valley pan off. Lesson learned the hard way.
