What Plugs do you use?

What spark plugs do you guys that have GT40P heads use?

I'm trying to find a good plug for my Daily driver, which has GT40P's, and I'm just looking for suggestions. Please PM me if you don't want to post them up here.

Thanks.

Nice...

Heat range? Part number? Anything? Stock replacement Explorer?

There next to impossible to find now. It would be easier to run a Autolite 764
