I have yet to do my homework on plugs for my new heads. I know that I'm going with autolites. Not sure on the heat range yet. Op go 1-2 ranges colder than the stock recommendation if you're running the spray. I ran 2 heat ranges colder on the e7's with a 150 shot. I didn't notice any side effects when running n/a.
