did you buy pre gapped plugs?

a few guys on here put theirs at .55 if they have boltons. stock is .60 for the LS1. i would go .60 to be on the safe side.

Are these the Delco Iridiums? If so, the gap on those is supposed to be .040, even for a stock motor. They are not the same as the stock platinums that came out of your motor.

Just learned something. I have Delco Iridiums and regapped them @.060. Luckily I haven't installed them yet. Why is the gap .040 instead of.060 for the Iridiums?
