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.
Yes, Rhoads VMax. I'm sure Vizard knows a thing or three, but you cannot simply arbitrarily decide to adjust a lifter off the bottom. They must be designed to do so. Telling people otherwise is wrong and can and will lead to bad things happening. I'm surprised he's making those recommendations. How old is he now?
