I just put in some Autolites in my car the other day to give her a little tune up and now I am running like I have a fat cam!!! I am at 9.5:1 compression with around 15 degrees timing and she is running like a champ except for the cammy idle. It didn't use to do this but I think I know why. I didn't gap the plugs when I put them in and the plugs I took out were gapped more than these new ones. I don't know why i didn't check earlier but Oh well. Anyway, my Question is for everyone is WHAT GAP SHOULD I BE RUNNING?? I have performer heads if that makes a difference. I just need to know what gap to run and everything should be cosher . I need a MSD pro billet distributor if anyone has one too by the way!!

Edit: My dimb ass threw the old plugs in a place I cannot find and hence the reason I ask this question!

i have gt40 irons and a true gt40 intake
running the plugs at .44 and fuel pressure at 40-42psi..it runs like a pony car should run.

.44-.54 either way the car will run good .44 if you drive it everywhere.

.37-.42 gives ya room to wear on

Just to let everyone know, .52-.54 works best with stock fuel PSI settings. I just tested out different gaps from .40 all the way up to .54. And the latter is MUCH better running.
