That gap should be 55thousands. And the stock timing is at 10*. You can bump it up and get a few more hp out of it. Try it at about 13 or 14*.

Spark plug gap is 0.052"-0.056". The motorcraft plugs are not pre-gapped. You will need to get the gap tool and do it yourself.

Stock timing is 10 degrees. With higher octane fuel you can try 12-14
