Hi Folks,
I'm new to the forum and looking for some advice on what spark plugs to run in my 545 stroker motor. I will be running a set of Ford Motorsport Super CobraJet "A" heads on a 10:1 compression motor. It will be a 94 octane pump gas motor for the most part. Any input would be greatly appreciated.

I use NGK-4554. Good stuff. 545 with 10.7 to 1 and Blue Thunder heads on 91 pump.
