sorry for steeling your post but i had the same ?......

Ok right now i have stock plugs what kind should i go with mod in sig. I am putting headers on in 2 weeks and will change them out.
I think you should go with the autolight 103's they are 2 range colder and should work with your car and if they dont since every car is different try the 104's.

I would try Autolite 104's gapped at .055". Unless you plan on going to a 3" pulley, then I would do 103's gapped at .050"...

Thanks!

I would go with 104's. If you end up coming up here, we can scan you too.
