I've searched the forums and cant seem to find any infor on what our stock AC Delco spark plugs are gapped at for the LT1.

I'm curious because my tuner is asking me to gap mine at 32 thou.
I have Rotofab dry filter intake, ported stock TB, and 1 7/8 headers with high flow cats. 93 octane.

Is there any downside to having the gap so small, at 32 thou without being boosted?

I'm asking because I want to buy some pre-gapped iridium plugs, to avoid messing up the iridium tips.

Thanks!
