Quote: Are you sure those are the correct style plugs for your heads, they look awfully short to me? My 440 heads take a long reach plug.
Then use just a drop or two of motor oil on the the threads, no anti seize, imo. Good luck to you!
Stock heads like Stu runs take short reach plugs, Edelbrock's take long reach plugs.. Small blocks take long reach... For Stu's car those look Ok but I'd still screw in a set of NGK's just to see were it puts him..
Thanks
