Hi Larry,
I think the short cut you found is correct and it can save some time when adjusting hydraulic lifters. I installed a permanent remote starter switch at the back of the engine bay on my Euro Pantera because I was having issues with lifters and it has helped me a lot. Since I have the remote switch I still do it the old way. If you still have a lifter tick after adjusting the valves you might want try this additive. After adjusting my lifters numerous times I still had annoying sounds. I put in two bottles of the additive below and the problem went away. The result was instantaneous and it was $20 well spent. I used two bottles because I have big oil pan.
