Post war sparkplugs

[90plus]

Hello,

I was wondering what type of spark plugs other members use for the following post war Douglas models?

Mark V ?

90 Plus ?

At the moment I am using the original Lodge spark plugs, but as they are beginning to become thin on the ground; I would like to change them for a modern equivalent.
