+1 u want copper plugs as stated above...I have mine at .035 for NA which is what sean hyland recommended in one of his books. He made the remark to gap it at .030 for a nitrous applications and of course u can't always be using nitrous so even though your not using it everyday it'll make it safer

That plug is one heat range cooler than the factory plug which will help aid in preventing detonation along with the closer gap. The car will be fine with those plugs and gap even if your not shooting the juice. One thing to keep in mind even with a 75hp shot, you're pushing the limits of what the factory tune can adapt to.

.028 is what i used for my old kit. not that its a whole lot different from .030. get rid of those bosch plugs, electricity takes the shortest root possible and the plus 4's are a gimick!
