On #1 in my aluminum head, the spark plug sticks out into the chamber about one thread on one side. In some of the others the plugs did not get to the chamber leaving threads exposed in the head. I fixed that problem while equalizing chambers, but I can't add on material to cover the spark plug thread on #1. Is this going to hurt anything??? Looks like it might get hot and glow, who knows.
