Plug gap with Edelbrock heads.

[Cobra351]

What gap you think I should use with what's in my sig. I was running Autolite 3924's but bought a set of 3923's. The 24's were a little hot.I am hopeing to help my pinging alittle with the colder plug.My compression is around 10 1/2 to 11:1. I allready run 93 octane and can just run 12* of timing.
Thanks,Phil.

I don't see any ignition stuff in your sig so I'll say .04-.045". If you do have a quality ignition then you should be around .05-.055"
