Are there any pros or cons to running all 9's in an NA with the normal NA upgrades(except for no porting of course)? From what I've read they won't do as well sitting in traffic right? I run around 48 miles to and from work each way with about 40-42 on the highway. I also have an MSD on the leads if it matters. I'm just running through twice as many 7's on the leads as I am the 9's on the trails. Also wanted to find those gappable motorcycle plugs some one was speaking of. Anyone with some good info?

I am running all 9's with a Crane Hi-6. I have had no problems. The plugs last longer than my 7;s did. Just as you observed
