Setting Valve Clearance using Vacuum Gauge

Thanks for all the input. So's you don't think I'm making this up, I read it in this ancient thread: http://www.moparchat.com/forums/archive/index.php?t-668.html "Ive even used a vac. gauge to adjust my valves while the engine is running ,I adj. to max vac. at idle if i want more torque," (Does anyone know who "PRO", the person who made that comment in 1999, might be? Location says Grand Junction , CO)

I also found a page that had a newsprint copy and transcribed version of an article describing much the same thing, although it was for a chevy 231 or something like that. I can't find the darn thing now. It did give specific minimums and maximums for the clearance, but said to maximize the vacuum within those parameters. Obviously not a good idea to have things so tight or so sloppy that metal bits are coming off.

Seeing is believing so I'll see what's possible (within reason) next time I adjust my valves.
