The NGK part number 2771 is the following:

Thd Size = 14mm
Seat = tapered
Reach = .460"
Hex = 5/8"
Resistor = Yes
Gap = .039"
Heat Range = 5

It is also a projected tip.

Go to: Spark Plug Reference Website

Enter the above info in the pull downs and then hit "Find". Give the site time to register each pull down selection you make. You will find your NGK plug along with some other options.

I started with the Champion V59C race plug in my Dart Iron Eagle heads but had too much fuel and too little ignition to keep them from wet fouling. I switched to AC Delco R43T. It's close to the NGK part number you listed except it is hotter and not a projected tip. Unless you are running rich like I am, it would probably be too hot for you. Mines a blower motor so I want to stay a little rich.

Hope this info and website helps you.
