I know everyone has an opinion on spark plugs, I would like to hear some of them on which brand I should use with my engine. I have a 440 with 10.5 - 1 compression, stock heads and pistons, mild Bullet cam, Edelbrock Performer 440 intake and a Holley 750 carb. I also have Doug's Headers and MSD 6AI ignition. This is only used for car shows and occasional drives around town. P.S. I like to 'blow the carbon out every once in a while'.
