I honestly don't remember but I know it's something he does on a regular basis. By big block solid roller standards, it's really a baby so I don't think it was a real consideration. Solid roller lifters are a wear item in all engines, especially big block chevys. I knew this since day one and that's why I've kept a fairly close eye on them. The valve spring pressure is likely what led to the failure. That or it's one hell of a conincidence. I've read a bunch of threads on solid roller failures and I don't recall valve spring pressure coming up but I feel it's likely the real issue. One thing to remember is a solid roller has lash while a hydraulic roller rides on the lobe at all times.
Swapping springs and replacing/rebuilding lifters are going to be part of the maintenence and I knew it, just didn't know the interval. It almost bit me.
