A while back someone put on a thread what spark plugs are a correct fit for gt40p heads. Wondering if anyone would like to help me out, thanks in advance.

I always ran regular copper autolite's....1 step colder 764's or 104's, 2 step colder 763's or 103's. Had good luck finding the cheapest at walmart.

When you go to the parts store ask for 93 Cobra spark plugs...that is how I did it. I always forget/lose the part number.
