I use ac delco R43xls in my 6037 edelbrock heads. They're one heat range colder than stock, so they're good for juice. I've got a NOS dry kit with an 80hp shot (125 soon), and was told to gap them at .045".
You'll have to experiment a little to find out what's best, but that should be a good start. |

This is like the basic rule : If you use a power adder, go on range colder plug (to start)and close up the gap. .035 to .040 is what I would do. The brand is your preference.
