I've also built a Ford Racing 514 from short block. I don't have an NGK part number, but Ford Racing recommeded I use Motorcraft AGS-32C spark plugs. They like this heat range for the 514 engine. Perhaps you could find a cross reference to an NGK number? I can't give you any feedback on this plug because the car's not on the road yet. All I can confirm is that the engine runs with these plugs!

Good luck!

Go to www.ngk.com

If you have the 18 mm tapered seat plugs(??) there isn't a large selection. Click on the "411" (information) logo and do a search by entering various bits of information. There is a lot of solid information on this site.
