shimming hydraulic roller lifters solid

I don't think there really has been a problem with solid roller lifters failing, other than the odd one that uses needle bearings. The problems has been with the hydraulic portions of that family of lifters, as well as some skanky face profiles on the non-roller lifters. I think the effort is to be able to reduce the cost of getting into a solid roller, at least it would be for me. I'd be running it on the street so would be more of a 6/10ths type of effort than all out race with .800" lift.
