They are the same I think, I had them pull up the motorcraft for the 98 and got a crossreferenced number for autolite, and gapped them at .054.

When I did the PI swap I really needed it tuned. It was running very poorly before, and it made a hell of a difference afterwards. I always suggest anyone about to do a PI swap to not do it until you can afford to get it tuned.
