I have not been able to come up with the valve timing graphs, but I did find this test method posted by Dave at Dart Auto. What do the experts think about testing with this method?
“An easy way to check is to install your cams and get #1 set up to about 30 BTDC on the overlap stroke. Turn the valve adjust screw in 1 turn and see if you have interference as you turn it till about 30 ATDC. If not back the engine up and turn it in another turn. Each screw turn is 1mm. If you get to 3mm you are fine for sure. You can probably run it as close as 1.5mm. I have checked this method against the clay method and the solder method and found it to be at least as accurate, but it does not tell you where the interference is like clay will.”
