Spark plug gap

As with many issues this has been covered as far back as 98 on the mail list. (and maybe earlier) Unfortunately the archives on the Club pages only go back to 2000.
This is the earliest found there:

Thanks, fellas. The new plugs had the same end as the old ones. I torqued them to 22 ft/lbs, per the FSM.

At least you don't have to worry about the gap effecting the dwell or timing.
Ah the 60s ... =D>70s.
Some things really have improved.

A little antizieze on the plugs and a bit less torque

Definitly used antiseize. Here's a pic from both manuals. The larger one says 22 ft/lbs, the supplement says 19 ft/lbs. Which one are you suppose to follow? The larger manual is under the 5.7 vin J engine too (ZR-1).
