Best spark plug for the 8ba Flathead?

Can you guys tell me what spark plugs you guys are using in your flatheads with Edelbrock fined heads?
Thanks

 

NGK-B6L....................the Best!

Autolite 216L were made for the car, They can't be beat.
Avoid Champion.

search 280 is the best.

 

Just ordered some B-6L for my 1115 edelbrock heads but they are way too short to get anywhere near the combustion area. The edelbrock heads would seem to require a much longer plug to remain unshrouded. I am thinking R12yc champion ( I know A.B.C) maybe there is a better long reach option. The heads have not had relief around the plug base .Probably should have??
