Default AU XR8 200kw spark plug gaps?

HI all,
Bought some replacement OEM Motorcraft plugs for the ute but they have come out of the box gapped at 1.2mm. Seems pretty large to me and cant find a specification in the owners manual. OK to run or??

I have ran NGKs with the recommended 1.3mm gap on a couple of AU V8s now for 6 years. Never had a drama.

Plugs below are 2.5K km old.


Cheers

Thanks everyone, I've just whacked them in with the 1.2 gap they were already set at. I suppose being OEM replacements they were bound to be right, just looked a little big compared to an I6 which Im used to.
