.035" get the job done fine for a performance application. .040" is good. .060 is way too much.
If when you set the plug gap at .035" and the ground strap goes past the center electrode you can trim the ground strap length as required.
Trim the ground strap so it is just short of the far edge of the center post.
File smooth any sharp edges of the ground strap end after trimming.

|ericnova72||.060" is mostly an emissions spec, performance specs are between .025" and .045". .040-.045" would be appropriate in your case. Running an extremely large spec like .060" is just hard on the secondary ignition system parts - the cap, rotor, rotor button, coil, plug wires as it raises the resistance at the plug a great deal with no real positive effect on engine performance.|
