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

Hey Joe, thanks for the update. It's good to know I can expand my search range for the P&G Valve Gapper maybe this way I can find one less costly and easier. still using the old fashion feeler gauge method.

If you have performance heavier valve springs (ie) 95# or 105# the Gapper will not work on them as the performance spring OD is larger than the stock 65# valve spring, do not mean wire size. Also the performance one piece spring retainers are larger OD than the stock 2 piece spring retainers. The gappers horseshoe clips are too small to seat properly over these performance retainers and springs.

One piece retainers supplied with Verne Schumann's "police upgrade kit" (which includes heavier springs) same OD as stock 2-piece, and will still fit the "X" adapter foot.
