It varies but there should be a small gap. The rebuild instructions for the 4GC start on page 15 in the service article here See if the gap is as specified in the fast idle adjustment step 5 on page 17. As real world conditions warrant, the adjustment could vary the gap slightly.

There is also a training manual for the 4GC that goes into a bit of detail on how that section functions and how adjustments determine where the final gap will fall.https://packardinfo.com/xoops/html/downloads/1955_4GCTrainingBook.pdf
