Hi,
I like AC at the standard .035,but ND are cool too,similar gap. What's the big deal? I almost never have a misfire. I'm happy with this at my configuration.

I run AutoLite's gapped at 0.030 and was good up to 28PSI.

I started misfiring around 23PSI with 0.035 gap and a new coil.

Hi,

I agree with both previous post to answer your question about plugs and gap but, there's no need to change plug brand. The AC Delco R42LTS will do what ever you need. As far as gap goes, at 18 psi a tight 0.035 is just fine. You can go to 0.034 if it makes you feel better but, you will see no change in performance. Now, if you go to 20 psi I would recommend 0.034.
