World Formula vs. Animal head spark plug

[mike97760]

I just bought a World Formula cylinder head to put on my open Briggs Animal engine. It has done just fine using an Autolite 3910x spark plug. Which spark plug does the World Formula need? Alky motor.

Doesn't say methanol specific .

Thanks Flattop, TS Motorsports, and our dear old friend Al. Hope Al is having a blast racing in heaven.

Mike, I use either the oem Briggs plug or the 24 or 27 Denso plugs on our alcohol WFs used on jr sprints.
Sarah keeps the Densos in stock if you need or you can pick them up locally.
