The reason non hydraulic lifters wear out.......is because there is a space...( the valve lash) within which the lifter bounces......which in turn causes the wear of the lifter face and the cam.
With a hydraulic roller, the wheel on the bottom of the lifter is kept in constant contact with the cam lobe, just a wheel continuously running on a flat surface...........a solid roller lifter has the same problem as
solid roller in that it also has some lash which allows the lifter wheel to leave the surface of the cam, allowing it to hammer itself to death.......this is why the solid rollers die.........in a small Chevy and I am sure with some work it can be made to work in the Fords, there is a kit called a Rev kit .....nothing new....which is essentially some small pressure springs between the head qnd the lifter....solid lifter which keeps the lifter in constant cantqct with the cam........the other huge benefits of the are the the valve spring is not tqsked to control the lifter, and the valve spring can be much lighter pressure alleviating a lot of stresses on the valve train.....
