All three of the Autolite plugs, AR92, 93, and 94 are .708 reach and overall length the same. The difference in the 3 is the heat range of the plug. If you need a shorter plug from the head surface to the plug terminal you will need to go with a shorty plugs from Accel which are approximately 1/4" shorter.
