shimming hydraulic roller lifters solid

Vizard's method works. I believe the later Rhoads lifters [ are they called V lifters? ] work on the same principle. However, they are still a hyd lifter & work as such. So still able to pump up, or bleed down. If you convert to sol lifter operation, none of the above bad things happen, plus you get a better idle because of more positive valve seating.
