So to get a good reading on your plugs you cut the threaded part off, right? The pics I saw looked like really clean cuts, is there a tool made for this? Didn't look like your typical angle grinder/dremel job in the ones I saw.

A lathe would be the best, but like mentioned it's not something alot of people have.
Air tool with a cutoff wheel, that's your best bet. Dremel will do it, but you'll be there a while if you've got a bunch of plugs to do and you'll go thru the disks pretty quick.
Easyest at the track is Dewalts 18V battery angle grinder with a 6" cutoff wheel. just enough power to cut but not grab the plug and throw it at your car LOL. a vice would be nice but were not that high tech yet..... vice grips and the cutoof wheel...
the reason the cuts look good is a cuttof wheel will not cut porcelin so it just cuts the metal

If you do not have a cut off wheel a hax saw will work but its alot of work..
