What plugs to use with KB?

[pwcracer]

I switched to edelbrock heads and I am still going to use the KB with them. Do you guys know what plugs to run with this combo, I think the KB rec to go one range colder, but I don't have my old plugs around to see what number they were. I also wasn't quite sure if they would work with the new heads

thanks

Go to the Edlebrock website and see what plugs they use. Buy one heat range colder.

I now use Denso IK20 Iridium spark plugs, I tried IK22 but they were way too cold. I'm running a KB Blowzilla @8psi on 91 Octane with Edelbrock 60379 Heads, 2.01" intake, 1.6" exhaust valves, 60cc.

Good Luck, Don
