I cleaned and oiled all the parts and it appears that the #2 barrel and the H base will work to adjust the lifters with the engine not running.  The H base fits solidly over the valve spring retainer but has little surface area to sit on and I'm unsure how solid it would be at idle.  A bit of lathe work will make these mating surfaces wider and should work with the engine running.  I set it on a spare head to see how it works and compare to the pictures.  Looks like an easy tool to use and since I adjusted my lifters a few weeks ago, I will have to try it and compare my results.  Thanks again for the help.   J
