Default plugs

is the correct gap for spark plugs for a 97 ford 4.0 v6 0.061 to 0.068 inch?? I had a p0305 failed code inspection for my truck and i changed all the plugs and wires to fix this now its seems like my alternator isnt working properly....loud clicking and rough idling/ hesitation

Really no need to change them unless they are causing problems.
